How to disable virtual memory / swap files
Authored by: Antirty on Jan 18, '09 12:26:14PM

I would like to disable virtual memory as Firefox keeps running slowly whenever I have loads of windows and tabs open, when I look in Activity Monitor it show it is using upto a about a gigabyte of VM... why it does this I do not understand as I have at least 2GB of RAM unused and available to use. If I then run another browser such as safari whilst still having the same slow running firefox open Safari or alike runs at full speed.. firefox is prone to slow scrolling and poor performance due to this. Safari doesn't do this. Though I prefer to use Firefox, but I am liable to stop using it if this problem remains....

I assume if I turned off VM then Firefox would have to use the available RAM. There seems to be no way of changing the VM use within system preferences or in Firefox preferences.

I am running the latest version of Firefox and Leopard 10.5.6 on a Dual G5 2.0ghz with 4GB of RAM.

I used to get this same issue on Tiger on my G4, but it stopped doing once I changed machine due to system performance improvement, but clearly the problem is the same as I am now finding out when needing to have a large number of tabs and windows open. There is no need for my system to be running slow when it's hardly using any of it's resources/power.
