I did the same; same config, fresh tree, reboot between the test.
The machine is a (single-processor) AMD K6-2/400 with 256 MB RAM.
Here are the results:
2.4.18-pre3 real 7m55.243s
user 6m34.080s
sys 0m27.610s
2.4.18-pre+H7 real 7m35.962s
user 6m34.270s
sys 0m27.700s
2.4.18-pre3-ac2 real 7m39.203s
user 6m34.110s
sys 0m28.740s
Ingo's scheduler rocks, it runs like hell (and is absolutely stable here) ;)
