swap file logic

[krusty]

I know there have been many discussions on this topic but I have a new question. Some say that you need 1/2 as much or twice as much as the amount of ram you have. Lets say I have 64M ram.. make my swap file a fixed 128M = 64+128= 192M. Fine I can understand that. Well now lets say I add another 192M & have 256 M ram. Why not just turn the virtual memory off?.

That is exactly what I have done lately. The only problen I have had is that Starcraft tells me that my system is not configured properly. It will still run without any problems.

I have noticed a definite increase in system responsivness as there is no longer that HD noise/time whenever you do anything significant.

I'm just interested in in the opinions available here.

Thanks ,

By the way,..... my available memory has not dropped much below 100M whenever I have been able to view it.

Download "Cacheman" from www.outertech.com (http://www.outertech.com) , install it, configure it for "Power User" and come back to tell me if you impressed http://www.sysopt.com/forum/smile.gif

Hi Nd,

I know about cacheman but I am just saying that using the logic people here use to set a virtual memory size, wouldn't it reach a point where if you added more ram then you may as well have no virtual memory...i.e. no need to use something as slow as a hard disk when you can just add that same amount of ram to the system instead.???

Am I missing something???

You're theory is correct with the exception of some programs insisting on writting to the swap regardless of the amount of ram.

Ahhhhh,,,I wondered if there would be some such problem.

According to the Diskeeper 6 Trial I just installed, I have a fragmented Swap File even after reboot.


I defragged another partition (d http://www.sysopt.com/forum/smile.gif then set up the Swap File @ min-384 max-384 and the machine flies now. Photoshop 5.5, Corel Draw 8, AutoCad 2k open in under 2 seconds.

BTW I set everyones to 384 min/max no matter if they had 128 or 256MB and they all gave praise as their machines are flying now.
I believe what helped alot was that its on its own freshly defragged partition.

..I saw a tip here a couple of days ago as to how to force windows to use the physical ram before the swap file ( adding a line to the sys.ini file ) and when I did that while letting windows manage my swap it never made a swap file (768 megs RAM...guess I didn't need one) but since I hate trouble I set my own to 512meg min/max...so far as I can tell it's never been written to...seems to work for me and if I ever need more that the 768 physical RAM I'll know about it...
