According to Dave, with his patches you should even outperform that if 
you got faster CPUs :-)

Emmanuel, where is the "mk1BFiles" Benchmark? We're planning for a new 
hardware this year, so this would be a good time to run it.  Could I 
have the script?

The output misses the time "ls" took, but I can one can calculate that 
from the next test start, so 9:30-7:20 = 2:10, is that correct? Two 
hours to just see all files, ugh. I guess it will take some years until 
we want to have such a filesystem. Either hardware must become quicker, 
or another wonderful new patch is needed.
