I also login in to run setiathome but then I start a script called 
runseti # and it starts with what ever you supply instead of the #. This 
allowed me to capture all of the state.sah's before I ship them to 
Berkeley. I can go back and look at the peaks and what ever. I was using 
the processing times to compare systems. I concatentate the finished 
state.sah on to the end of a file called result.log. When it gets above 
400KB and I notice it, I rename it and gzip it to make it smaller.

There is quite a large difference between wu's but after you have run 
around a 100 or so, things start leveling out. I have two P-II 400s that 
process with a 10% difference in rate. I saw the 10% at 100 wus and it 
was very close to the same rate when they had each processed 1000 wus. 
Never did figure out why they are different. I assume one mb was faster 
than the other and eventually stopped being curious.

Some time ago, I tried overclocking a Celeron 300a and found that 
building XFree86-3.x.x and running setiathome was too much and cooked 
the Celeron. The build required several hours. I could do build worlds 
just fine but the build of XFree86 stressed the system more.
