Are the circulating optimization techniques sure to be credible?
Computer performance optimization, overclocking, and transformation are what every DIYER user pursues, but many users "blindly" optimize the computer, and even improve performance through "perverted" transformation. As a result, what they get is a hypocritical psychological achievement "satisfaction". In fact, the performance not only does not improve, but instead occupies more resources of the system. In addition, in order to attract more readers, many magazines and websites sometimes publish some optimization techniques that have not been verified and tested. At the least, they are useless and at the worst, they cause readers' computers to be damaged. In the "mass movement" of computer optimization, solutions that do not advance but retreat frequently occur. In order to awaken these so-called "renewal" hardware performance through simple optimization, we have listed several typical performance optimization tricks for your reference. Next time you see the optimization method, you might as well think about it to prevent being deceived.
One of the tricks: ADSL bandwidth 1Mb to 2Mb
Scam phenomenon
If you search online, there are really many articles about ADSL optimization. For example, modifying the registry and ADSL optimization masters can improve the Internet speed, even reaching as much as 20%. Is it really such a good effect?
Fraud Analysis
Is soft optimization really useful? Of course it is useful. But from the test, we know that the effect is not obvious. Taking modifying the registry to optimize ADSL as an example, entering the registry HKEY_LOCAL_MACHINESystemCurrentControlSetServicesVxDMSTCP, changing "DefaultRcvWindow" to "371712" can increase the network bandwidth to 2Mb/s. We know that broadband providers provide ADSL 1Mb/s bandwidth speed (theoretical speed), but in fact they cannot reach this speed. Even if the speed is improved through soft optimization, the maximum speed can only be increased to close to 1Mb. How can you get 2Mb speed for free? No matter how you toss, it is impossible to optimize it to speeds of more than 1Mb.
The author conducted a comparative test before and after the modification registration. Before modifying the registry optimization, the speed of using FlashGet to open 10 threads to download a 10MB file is 95KB/s, and after optimization, it only increases by about 0.2K (that is, 95.2K/S). In order to prove the trick of soft optimization, the author used "ADSL Optimizer" to conduct pre- and post-optimization tests (the test environment is /gb/broadmeter/SpeedAuto/). The speed before optimization was 113.12K/S, and the speed after optimization dropped to 105.04/S. It seems that not only has no effect, but turning on the software will take up resources and slow down the entire network speed.
The comparison test speed before and after optimization has not changed substantially, and speeding up is basically a big deal. The 6KB/s gap can be considered as test error.
Scam 2: No open P4 level 2 cache
Fraud phenomenon
In Windows XP system, the CPU Level 2 cache is not turned on by default. To improve system performance, we can enable it by modifying the registry, or using software such as "Windows Optimization Master". Or run the registry editor, expand the HKEY_LOCAL_MACHINESystemCurrentControlSetControlSessionManagerMemory Management branch, double-click "SecondLevelDataCace" in the right window, and then directly fill in the second level cache capacity of the CPU used by the current computer in the pop-up window.
Fraud Analysis
Is this really the case? We found “Do not change the SecondLevelData in Microsoft’s knowledge base
The article points out that some third-party data claims that modifying the value of the SecondLevelDataCache key can improve system performance is incorrect. The value of the second-level cache is detected by the operating system and is completely unaffected by the SecondLevelDataCache value.
The so-called Windows XP system requires users to manually turn on the secondary cache is wrong. Windows XP system reads the CPU's secondary cache value based on the hardware abstraction layer. The value of SecondLevelDataCache is only read when the read fails. The default value of SecondLevelDataCache is 0, which means that the secondary cache is 256KB, rather than indicating shutdown. Therefore, the CPU's Level 2 cache is enabled at any time, and there is no need for users to modify it themselves.
