Yes it sure does -- the original timings were with a 2.0.36 kernel. I
upgraded that machine to a 2.2 kernel and did some timings (time
to load netscape on a freshly booted machine).
page-cluster time
1 10.62
2 8.38
3 7.07
4 6.4
5 5.53
6 5.05
7 4.78
I used a stopwatch so there is certainly some error in the timings.
