Memory Optimizers

[hari]

Hi all,

Read http://www.winnetmag.com/Windows/Articl ... g/2/2.html

I agree to it almost.

I might have written operating systems for a living ...

In a virtual memory system, it makes no sense to "defragment" physical memory. Any physical memory page can map to any virtual memory page with no loss of performance.

In a virtual memory system there is little advantage in having free physical memory. It is better to keep pages that have been removed from the working set in physical memory, as XP does, until the memory is needed for some other page. This is why the modified page writer runs only occasionally.

It makes no sense to do anything that will force pages out of the standby or modified lists unnecessarily. A hard page fault (one from disk) takes something like 100 times as long as a soft page fault (one from the standby or modified list).

So, I agree with your choice not to support a "memory optimizer" even though some competitive products do.

Ya , I agree. We could easily have improved our freeware free ram xp , added a few bells and whistles and sell it . But that would be against what we believe, as we don't use it ourselves. You know, we sell only what we use ourselves.

I read and agree with it. But one particular program that does more than manage memory is Outer Technologies Cacheman V 5.5 (freeware & shareware), and the excellent CachemanXP V1.1 (shareware)
