I believe the default virtual memory size is 80MB (OS 10.1 & 10.2, anyhow), so your 67,108,864 would be non-standard and low. If the 1st swapfile (number 0, like yours) gets filled up, I believe additional ones are allocated 80MB at a time. If you have a lot of RAM (384 is not "a lot"), depending on what software you are using you may never be using the swap file anyhow. > I finally did this in my terminal on my 'book, and got this result: > ls -l /var/vm > total 131072 > drwx--x--x 12 root wheel 408 30 Apr 17:59 app_profile > -rw------T 1 root wheel 67108864 5 May 07:02 swapfile0 > > what I don't know, is whether it's good or "bad" to have a 6 MG > swapfile like that? . . .
