Why don't you use the -b option with the mean size of all the previous runs that you did with the default -p option? this way you'd avoid throwing away all the previous results and the new ones would be more reliable. I'd prefer if you would allocate always the same amount of memory, the variations are not huge, so I guess it's better to reduce the userspace noise. In particular I'm interested if you can see significant performance variations between pre5aa1 and pre6aa1 and pre7aa2. I'm also testing here (mainly Linus's 40m kde test to verify interactive response on real life that unfortunately cannot produce raw numbers) and I didn't had much time to spend producing numbers since there was also some bug to fix utill yesterday (should be all fixed in pre7aa2). The recent changes were mostly in function of the kde mem=40m workload that is pretty well usable for me in pre7aa2 (xmms never skips one beat while playing mp3 even if mem=40m and browsing the web with konqueror is fluid, mozilla also is usable but much slower than konqueror with mem=40m because it's a true memory hog at least when flash starts and of course it shares less libs with the rest of the desktop).
