Here is a controversial article in which the writer poses his opinion and those of others, to debunk some of the more popular performance myths that surround the Windows operating system. The article is well written and a definite read for anyone who is considering putting down their hard earned bucks for what he calls ‘snake oil’ solutions to Windows performance problems.

Some of what the article states is subject to opinion:

Disabling QoS to Free Up 20% of BandwidthThis tip made the rounds with people believing that Microsoft always allocates 20% of your bandwidth for Windows Update.

Clearing Out Windows Prefetch for Faster Startup

The Prefetch feature in Windows XP caches parts of applications that you frequently use and tries to optimize the loading process to speed up application start time, so when a number of sites started suggesting that you clean it out regularly to speed up boot time it seemed like good advice… but sadly that’s not the case,

Cleaning the Registry Improves Performance

The Windows registry is a massive database of almost every setting imaginable for every application on your system. It only makes sense that cleaning it out would improve performance, right? Sadly it’s just a marketing gimmick designed to sell registry cleaner products, as the reality is quite different… registry cleaners only remove a very small number of unused keys, which won’t help performance when you consider the hundreds of thousands of keys in the registry.

Clear Memory by Processing Idle Tasks

By this point you should be starting to get the picture… if something sounds too good to be true, it likely is. This well-traveled tip usually claims that you can create an “undocumented” shortcut to Rundll32.exe advapi32.dll,ProcessIdleTasks that will clear out memory by processing all of the idle tasks wasting memory in the background.

Enable SuperFetch in Windows XP

Somebody decided to start spreading the myth that you could enable SuperFetch in Windows XP by adding the same EnableSuperfetch key into the registry that Windows Vista has, and it spread like wildfire. Naturally, this tip was completely bogus

So here is what I would like for you to do. Go over and take a look at these myths and see what you think. I want to get some opinions and see what the readers here think. Quite frankly, some of the listed myths were surprising to me. I guess I have always felt that cleaning the registry was a good idea, but is it?

Any way, share your opinions.
