I run your test, the numbers seem quite equal to yours, but during the test my system became unresponsive like hell. Switching desktops (from web to evolution) took more than 20 seconds (probably due to swapping, I have 768MB RAM), subsequent switches took up to five seconds. I could see the drawing while I tried scrolling in evolutions' folder list. vim took ages to load etc. pp - all in all very sluggish.
