10.6: Completely Disable Virtual Memory in Snow Leopard

[Trouble]

This works. I've been running my Hack with no VM for an hour or so and it is snappier. Much snappier. I do have 12GB of RAM and iStat running in the menubar so I can see if the machine gets close to hitting a hard ceiling.

This hint is the result of an experience I tried in the last few days. It involves disabling the dynamic pager daemon and stop using virtual memory at all in Snow Leopard. I don't recommend doing it in previous OSX versions, or if don't want to take risks. Advantages, in my case, are obvious, and, so far, with no issues at all.

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist

Hmmm...I might try that. i've got 16gb on my 2 desktop machines.

OK, so how would I undo this should it not go so swimmingly for me?

Nevermind. The answer is in the article...

I thought if you already had a ton of RAM you wouldn't need to worry about VM in the first place.

Thanks. I have 14GB in my MacPro. I'll have to see if it helps.

Great tip, thanks! I'll try it later, after catching up on my delinquent CCC backup....

Trouble - what does the system memory panel of the activity monitor look like now? Can you give us a screen shot?
