If you have been interested in the tests about speed, updated results are at:

On the average, Tiger is 4 times slower at doing "do shell script"
than Panther or Jaguar. You'll be twice faster (let alone much
richer) with your 1 GHz G4 under 10.3.9 than with a brand new 2GHz G5
under 10.4.2.
I would like to reply to Michael: is that only "do shell script"? I
don't think so, because the other data, the times for "beep", still
show the same trend, look at the average numbers (operations per Gc):
10.2: 979 op/Gc
10.3: 845 op/Gc
10.4: 498 op/Gc
The discrepancy is not as obvious because the times implied are very
small. Yet we've still got our fastest Panther (3000 + op/Gcycle)
which is more than 4 times faster than our fastest Tiger (680.)
The script that we made public [1] extracts the data that users sent
and makes them into clean columns of numbers, so it's fairly easy to
change to make whatever other plot that one would imagine relevant.
