Temporary Disabling of Sophos on iMac so I can run Avid Pro Tools

Torchlight

How do I temporarily disable Sophos so that I can run applications like Avid Pro Tools?  Sophos must use enough RAM in the background to choke my Pro Tools application when the session is using heavy duty plugins.  I noticed this the other day when I was running a session with some fairly heavy plugins.  I would get the "increase CPU limit" message in Pro Tools.  I uninstalled Sophos and have no more issues.  My machine is an iMac (Core Duo) with 4GB of RAM.  It has never had problems running sessions with high track counts and heavy duty plugins.  I love the Sophos software but I can't use it if it's going to degrade my Pro Tools performance.  Is there a quick way to temporarily disable Sophos so that is not using any processing power while I am running ProTools?

Thanks.

    To answer question 1: in About This Mac, click "More Info..." and then click the Memory tab.  Then click the Memory Upgrade Instructions link.

    The Memory tab tells you what sort of memory you can use; as you guessed, you'll have to replace your existing memory with 2 4GB sticks, which will top you out at 8GB (max allowed on your iMac I believe).

    Last answer: it doesn't stop Sophos from doing ANYTHING... however, the way resource management works on OS X, with the on-access scanning disabled, it should in no way hinder Pro Tools.  Disabling the daemons (Intercheck, auto-update, etc.) won't make any appreciable difference to what you're doing; the OS already optimizes that.  If you check your LaunchDaemons and LaunchServices settings, you'll see that there are many many other services running as well.  You could in theory disable all of them, but as the OS only loads them when it needs them, the net boost to your Pro Tools session is so insignificant as to be unnoticeable even by some profiling tools.

    One other thing you may want to do is temporarily turn off automatic updates as well -- if SAV starts doing a major software update in the middle of your Pro Tools session, this will definitely be noticeable.  I'd suggest turning off other services of this sort as well, including disabling the Apple Dashboard (or at least closing all dashboard widgets in dashboard view so they aren't running in the background).
