Are you using CacheSet?

I saw this software from sysinternals.com and got curious about it. But I am wondering if this was really needed or what really it is. I read the instructions but still could not really figure it out.

Anyone of you there already tried or are using this software? How to use it...instructions in details..pls.

 

Nope, because windows nt OSs do a great job of cache management and IRC that cacheset settings are lost after a reboot.

O&O Software (the people who do O&O defrag) have a cache manager called Clevercache which does allow settings to be saved.

But I am very wary of this product as their reasoning for "significant decrease in performance" is flawed.

"The more the file cache grows, the less memory is available to running applications. The result is a significant decrease in performance as requests for memory lead to the so-called "swapping" of memory. This occurs when unused memory segments are paged out to the hard disk's paging file. Because hard disk access is slow relative to Memory loss of performance is inevitable."

This is not true.
Firstly memory pages will always take presidence over the file cache, IF they are in use. The more RAM an application needs, the smaller the cache will get if memory is not available, infact nt will reserve SOME ram (from cache AND pages) for sudden increase in memory demands.

How can "unused memory segements", which I assume they mean pages reduce performance if they are not in use, swapping to a hdd will not slow a multitasking OS down but any significant amount, remember they said "unused" :|

I will dig out my links to windows memory management.

Anyway, I hope this will explain, why there is really no reason to play with cache settings in windows nt based OSs.

So in other words; this kind of software is useless, or even dangerous to your computers performance?
