Do I really need a swap file with 1gb of RAM

m/b NF7S; XP3200; 1GB [two units] DDR400 ram operating as Dual ddr 800mhz; two ata133 40Gig maxtor HDDs; xp home SP2 all updates applied:
Do i really need a paging/swap file? system suggests, as usual, 1.5x ram. 1536mb swap file???

Do i really need ANY swap file? i am advanced/intermediate level knowledge.

I also have 1GB RAM and haven't had a paging file for over a year. Done a lot of video rendering and photo manipulation in that time and not had any problems yet.

Me to,1Gb DDR and have never had a PF.I to run video rendering,games and a multitude of other progs without trouble.I used to have an app that measured peak PF usage,I ran it for weeks and the most my PF was used was 50Mbs,so disabled it.I think it should be possible during XP install to specify PF preferences,it is with linux.

So if you don't disable it, does it affect the system speed in any way?

here's the rub:
with a swap file there's always the possibility that windows will try to use the swap to disk even if the ram isn't full and i believe that [from my old IBM VM370 days etc...] is a bad overhead?

with no paging we are using bus/ram speed for memory but also we still need any new programme/data pages from the disk so we still have disk response delay?

the only other issue is when we actually run out of RAM. the highest use i have ever seen on task manager is around 700mb but that wasn't peak; once in the last 4 weeks i got "windows is short of virual memory" but nothing bad actually happenned.
MS always recommend a swap file.
Any MS swap file experts out there?

Truly excellent write ups (particularly the first) of why you should have a page file, and why you should let Windows (XP) manage it for you (for the vast majority of home users). Bookmarked.

not really, try it with 100mb

Did you read Chegs ®™ links? It explains it much better than I ever could.
