Re: Many Apps = System Slowdown?

I often have about 30 apps running (plus widgets and various OS-X apps
like mds and WindowServer). When first launched, the system runs
smoothly. But I notice that a lot of apps use more and more virtual
memory, the longer they run. It's not unusual for Activity Monitor to
show apps like Firefox, Photoshop Bridge, NetNewswire, and others to
eventually using 1 and even 2 gigabytes of virtual memory. When that
happens to a few apps, switching between apps can slow my system down to
a crawl. Quitting a few of the apps and relaunching them fixes it -
system response gets snappy again.

My question is... would adding ram fix this? (I currently have 2.25 gigs
of ram, running on a dual 1.8ghz G5 with OS-X 10.4.9).

You should have plenty memory. It's various programs that gobble up
memory to an extreme amount, some of them because of memory leaks. 30
apps is a lot, but I have fifteen. Safari is showing over 1 Gb of
virtual memory as is kernel-task.

I don't properly understand virtual memory, but I gather it is the
number of swap files and the page-ins and page-outs that are more
relevant than the birtual memory itself.
