Running benchmarks on a PC enables users to evaluate performance, to identify potential bottlenecks, and to choose effective system upgrades. Unfortunately, many users imagine that system performance is simply a matter of CPU frequency or memory capacity, which leads them to think that dropping in a faster CPU or more memory will automatically and immediately yield noticeable performance improvements. In reality, however, that is not always the case.

Though CPU and memory upgrades help in some situations, it often makes more sense to upgrade the storage subsystem or the graphics board if you're looking for perceptible improvement in system responsiveness or gaming performance, for example. If you ran a series of benchmarks and identified which components were holding your system back, you'd be able to choose the most effective upgrade for your current system--or determine which components make the most sense in a new system suited to your particular needs.

Several different types of benchmarks are available for evaluating a system's performance. Some use synthetic tests that don't necessarily reflect real-world usage, while others employ scripted tests that rely on actual applications and simulated real-world workloads. Some benchmarks assess the performance of a single component, while others measure total system performance. To best gauge the overall performance of a PC, consider running some combination of all of these different types of benchmarks, based on your usage patterns.

Benchmarking Do's and Don'ts

Before running any benchmarks, you need to consider a number of hardware and software factors, in order to avoid potential damage to your system and to ensure consistent, accurate results. We'll look at hardware factors first.

Many benchmarks place significant stress on specific components, so you need to ensure that all such components are in good working order, properly cooled (if necessary), and receiving adequate power. If you have a component that seems unstable or unreliable during normal, day-to-day use, subjecting it to a taxing benchmark could kill it. Also, an inadequately cooled or underpowered device that works most of the time may become unstable under stress. That said, we've run benchmarks for many years, and have had only a handful of components fail due to the demands of a benchmark test--and those components were likely defective to begin with.

On the software front, parameters for the operating system, applications, and drivers must be satisfied to ensure accurate, repeatable benchmark results. Windows (and other) operating systems proactively prefetch data and store numerous temporary files that could interfere with a benchmark, so it's best to clear out any temporary files and prefetch data before running a test. In Windows 7, you can find prefetch data in C:\Windows\Prefetch, and temporary files in C:\Windows\Temp and C:\Users\[username]\AppData\Local\Temp. If you have applications running, it may not be safe (or possible) to delete all temporary files, so restart your system and shut down any applications that may be running in the background before wiping out any temporary files.

You don't want applications or utilities that may be running in the background to interfere with the benchmark, so shut them down. This is especially important in connection with antimalware utilities, remote desktop tools, and downloaders that intermittently consume CPU, memory, and storage resources and steal application focus. Unless you're testing a system as it shipped from an OEM to evaluate the effects of background applications on performance, shut them down before running the tests. In the same vein, most operating systems load multiple services and perform maintenance during the initial boot process. Consequently, after boot-up, it's best to let the system "settle" and reach an idle state, with no drive or CPU activity, before you run a test.

Using the correct (typically the latest) drivers for a component is another important step to take to ensure that it is operating and performing optimally. This is especially true of graphics boards and motherboards/chipsets, where the wrong driver can significantly worsen the system's frame rates or transfer speeds and latency. Finally, confirm that the operating system is fully updated and patched to ensure optimal compatibility and to reflect the current, real-world OS configuration--not the OS as it may have shipped years ago.

Benchmarking Individual Components

Many components in a system contribute to its overall performance, but the CPU/processor, memory, graphics board, and storage configuration generally play the largest roles for most users. Which of these components is the most important in a particular case depends on the individual person's usage patterns, however. A gamer seeking the best possible frame rates, for example, will probably be better served by a faster GPU than by more memory. A casual user seeking a more responsive system may benefit most by upgrading a slow hard drive to a fast solid-state drive. You must decide which aspects of system performance are most important to you, tailor the suite of benchmarks to your specific needs, and then weigh the individual test results accordingly.

CPU/Processor

The most useful CPU benchmarks place a heavy workload on the CPU while minimizes the influence of other system components. SiSoft's SANDRA 2012 incorporates a few CPU-centric synthetic benchmarks that test a chip's performance with various mathematical workloads. The tests are multithreaded and generally scale with higher-clocked speeds and more CPU cores. SANDRA also provides results from other CPUs for easy comparison.

A Look At 19th Century Children In The USA

PHILADELPHIA — DINNER with your children in 19th-century America often required some self-control. Berry stains in your daughter’s hair? Good for her. Raccoon bites running up your boy’s arms? Bet he had an interesting day.

 

As this year’s summer vacation begins, many parents contemplate how to rein in their kids. But there was a time when Americans pushed in the opposite direction, preserved in Mark Twain’s cat-swinging scamps. Parents back then encouraged kids to get some wildness out of their system, to express the republic’s revolutionary values.

American children of the 19th century had a reputation. Returning British visitors reported on American kids who showed no respect, who swore and fought, who appeared — at age 10 — “calling for liquor at the bar, or puffing a cigar in the streets,” as one wrote. There were really no children in 19th-century America, travelers often claimed, only “small stuck-up caricatures of men and women.”

 

This was not a “carefree” nation, too rough-hewed to teach proper manners; adults deliberately chose to express new values by raising “go-ahead” boys and girls. The result mixed democracy and mob rule, assertiveness and cruelty, sudden freedom and strict boundaries. Visitors noted how American fathers would brag that their disobedient children were actually “young republicans,” liberated from old hierarchies. Children were still expected to be deferential to elders, but many were trained to embody their nation’s revolutionary virtues. “The theory of the equality” was present at the ballot box, according to one sympathetic Englishman, but “rampant in the nursery.”

 

Boys, in particular, spent their childhoods in a rowdy outdoor subculture. After age 5 or so they needed little attention from their mothers, but were not big enough to help their fathers work. So until age 10 or 12 they spent much of their time playing or fighting.

 

The writer William Dean Howells recalled his ordinary, violent Ohio childhood, immersed in his loose gang of pals, rarely catching a “glimpse of life much higher than the middle of a man.” Howells’s peers were “always stoning something,” whether friends, rivals or stray dogs. They left a trail of maimed animals behind them, often hurt in sloppy attempts to domesticate wild pets.

 

And though we envision innocents playing with a hoop and a stick, many preferred “mumbletypeg” — a game where two players competed to see who could throw a knife closer to his own foot. Stabbing yourself meant a win by default.

 

Left to their own devices, boys learned an assertive style that shaped their futures. The story of every 19th-century empire builder — Carnegie, Rockefeller, Vanderbilt — seems to begin with a striving 10-year-old. “Boy culture” offered training for the challenges of American manhood and a reprieve before a life of labor.

 

But these unsupervised boys also formed gangs that harassed the mentally ill, the handicapped and racial and ethnic minorities. Boys played an outsize role in the anti-Irish pogroms in 1840s Philadelphia, the brutal New York City draft riots targeting African-Americans during the Civil War and attacks on Chinese laborers in Gilded Age California. These children did not invent the bigotry rampant in white America, but their unrestrained upbringing let them enact what their parents mostly muttered.

 

Their sisters followed a different path. Girls were usually assigned more of their mothers’ tasks. An 8-year-old girl would be expected to help with the wash or other physically demanding tasks, while her brother might simply be too small, too slow or too annoying to drive the plow with his father. But despite their drudgery, 19th-century American girls still found time for tree climbing, bonfire building and waterfall-jumping antics. There were few pretty pink princesses in 19th-century America: Girls were too rowdy and too republican for that.

 

So how did we get from “democratic sucklings” to helicopter parents? Though many point to a rise of parental worrying after the 1970s, this was an incremental change in a movement that began a hundred years earlier.

 

In the last quarter of the 19th century, middle-class parents launched a self-conscious project to protect children. Urban professionals began to focus on children’s vulnerabilities. Well-to-do worriers no longer needed to raise tough dairymaids or cunning newsboys; the changing economy demanded careful managers of businesses or households, and restrained company men, capable of navigating big institutions.

 

Demographics played a role as well: By 1900 American women had half as many children as they did in 1800, and those children were twice as likely to live through infancy as they were in 1850. Ironically, as their children faced fewer dangers, parents worried more about their protection.

 

Instead of seeing boys and girls as capable, clever, knockabout scamps, many reconceived children as vulnerable, weak and naïve. Reformers introduced child labor laws, divided kids by age in school and monitored their play. Jane Addams particularly worked to fit children into the new industrial order, condemning “this stupid experiment of organizing work and failing to organize play.”

 

There was good reason to tame the boys and girls of the 19th century, if only for stray cats’ sake. But somewhere between Jane Addams and Nancy Grace, Americans lost track of their larger goal. Earlier parents raised their kids to express values their society trumpeted.

 

“Precocious” 19th-century troublemakers asserted their parents’ democratic beliefs and fit into an economy that had little use for 8-year-olds but idealized striving, self-made men. Reformers designed their Boy Scouts to meet the demands of the 20th century, teaching organization and rebalancing the relationship between play and work. Both movements agreed, in their didactic ways, that playtime shaped future citizens.

 

Does the overprotected child articulate values we are proud of in 2014? Nothing is easier than judging other peoples’ parenting, but there is a side of contemporary American culture — fearful, litigious, controlling — that we do not brag about but that we reveal in our child rearing, and that runs contrary to our self-image as an open, optimistic nation. Maybe this is why sheltering parents come in for so much easy criticism: A visit to the playground exposes traits we would rather not recognize.

 

There is, however, a saving grace that parents will notice this summer. Kids are harder to guide and shape, as William Dean Howells put it, “than grown people are apt to think.” It is as true today as it was two centuries ago: “Everywhere and always the world of boys is outside of the laws that govern grown-up communities.” Somehow, they’ll manage to go their own way.

Investigating Family's Wealth, China's Leader Signals a Change

From The New York Times

HONG KONG — His son landed contracts to sell equipment to state oil fields and thousands of filling stations across China. His son’s mother-in-law held stakes in pipelines and natural gas pumps from Sichuan Province in the west to the southern isle of Hainan. And his sister-in-law, working from one of Beijing’s most prestigious office buildings, invested in mines, property and energy projects.

 

In thousands of pages of corporate documents describing these ventures, the name that never appears is his own: Zhou Yongkang, the formidable Chinese Communist Party leader who served as China’s top security official and the de facto boss of its oil industry.

But President Xi Jinping has targeted Mr. Zhou in an extraordinary corruption inquiry, a first for a Chinese party leader of Mr. Zhou’s rank, and put his family’s extensive business interests in the cross hairs.

 

Even by the cutthroat standards of Chinese politics, it is a bold maneuver. The finances of the families of senior leaders are among the deepest and most politically delicate secrets in China. The party has for years followed a tacit rule that relatives of the elite could prosper from the country’s economic opening, which rewarded loyalty and helped avert rifts in the leadership.
