10.6: Completely Disable Virtual Memory in Snow Leopard
I've used this hint on my Mac Pro (12 GB RAM), and I see absolutely no speed gain. Running a large windows VM, re-computing some Bridge CS3 thumbnail, and other intensive task was as fast as usual. ---

10.6: Completely Disable Virtual Memory in Snow Leopard
I'm a bit skeptical about the measurement of memory when pager is disabled. I fact I don't understand the result: why is active memory stays low when I'm running big software? Take a look at these graphs: http://patpro.net/~patpro/pager_memory_all-day.png First one shows memory usage for a day, after pager has been deactivated, on a Mac Pro, 12 GB RAM. The spikes of memory consumption are due to Left 4 Dead 2 (around Fri 8:00, Fri 23:00). Active memory stays about the same value. Second one shows memory usage for a week: from 3rd to 8th of June, pager is active, after, pager is deactivated. Before deactivation, you can see the effect of playing Left 4 Dead 2 (every memory spikes). It clearly shows that playing L4D2 increases active memory usage by approximatively 2 GB when pager is active, and by nothing when pager is inactive. Note that on the 8th of June, uptime of the system was around 50 days, so active memory being so high is ok. ---
