Virtual memory comparison??

Hi,

I need to know how to do a benchmark test on virtual mem on
my PC. Let me know the following..

1) What things I have to change in the PC (in the Vm settings) ?
2) What software I use to perform the benchmark ?
3) How the comparison process is done ?

Thanks in advance!

use wintune which can be found at http://www.winmag.com/wintune98/.

just change your vm settings to about 3 times the amount of RAM on your computer. this can be done by going into control panel, system, performance and then virtual memory.

specify your own memory settings and then choose a harddisk , your fastest of course and then put the minimum and maximum at the same level. for example, mine is at 100 mb because i have 32 mb of RAM.

run wintune before the change then check wintune after the change. make sure that your always running minimal apps so that the computer is on a base level.

Assuming you have a hdd with at least a gig of free space I suggest setting the minimum to equal RAM size and the maximum at NO MAXIMUM.
This has worked very well on quite a number of systems with RAM from 16MB to 128MB.
If you don't have a lot of hdd free space then keep the maximum to around 1/3 of the free space available (maybe1/2 depending upon just how much is available).
The problem here is that if you have a small hdd ( under 1 GB) then you need to be careful that you don't tie up all of the free space.
Norton Utilities has an excellent set of routines for fine tuning your 'puter. Just make certain you have the Utilities designed for the o/s you are running.
Virtual memory is effectivly "Hard disk" so check your hard disk performance! Software already mentioned such as WinTune will test HD performance. Also ensure that the swap file (The file which windows uses to create it's virtual memory) is de-fragmented for optimum performance. Depending upon Windows version you will have different ways of doing this. One tip which I was given, If you are setting a system up for the first time then create a partition on the HD which is about the size of virtual memory that you will require (I agree with the 3-4 times memory size mentioned above) and use that partition for virtual memory and nothing else. Altering VM settings can cause problems particularly with Win95 (and Win98?) so be prepared to put it back the way it was as some programs seem to expect unlimited VM. Also don't attempt to alter partitions on an existing HD unless you are properly backed-up or can afford to lose everything. VM is more important the less "real" memory your system has.

Sorry , This is not the answer I was looking for.
Read my Question.
anu : you haven't made comments on jimat and my comments. would you like to do so?

I suggest using bushhead idea. Only defrag the drive first as this will keep your  virtual mem swap file defraged.
