Re: OS X VM

[joeballo]

You will always have swapfile(0) 'cause that is the default swap file that is created at boot time and it will always be 80 MB. Hopefully your system will not need to create swapfile(1)... ... n. But since you can't do anything about it I wouldn't worry too much :-) . I have 768 MB of ram in a beige G3 and seldom go over swapfile(0). The programs that seem to require large amounts of VM are VPC and Photoshop. And yes there is a way to turn off the VM system but I have never tried it and I don't know if this will corrupt the rest of the system. VM is really a integral part of Unix systems. Even after you have all of these swapfiles they tend to go away as the system releases RAM. Logging out and then back in will also reclaim memory. Of course restarting will reclaim all of it and set you back to swapfile(0).

Utilization of VM in OS X [forgive me if this is all old hat] is

and goes up in 80 MB increments as needed, so 500 MB for a separate VM
partition would accommodate 6 swap files. I have never seen mine go
above 4 swap files. You can check this is /var/vm. In those cases where
it has gone above this it has invariably been associated with a runaway
app or some such. Restarting the OS has taken care of the problem. If
you never see more than one or two swap files and if top does not show
appreciable page outs there is really no need to have a separate swap
partition.

Thanks for the command info to show swap file size. Oddly enough mine shows swapfile 0 !! I do have 624 mb of ram could that be the reason why or is something else going on here? I have never tried to mess around with swap file at all son have not changed the size etc. thanks Will S
