AIM7 is a mixture of very small jobs from the AIM9 benchmark.
The Tasks column is the simulated load average.
A copy of the workfile for the custom load is at:
http://home.earthlink.net/~rwhron/kernel/workfile.custom
There isn't any notion of fairness here, just speed.

AIM7 dbase workload
This load has more synchronous writes. Supposed to be a little
like a database.

Below is the average of 25 runs. That's why things like page fault
show a decimal point where normally lmbench doesn't. BTW, would anyone
be interested in seeing lmbench for a quad xeon running Linux, and
a couple of Sun SMP boxes running Solaris?
The report comes from a tweaked lmbench getsummary script
http://home.earthlink.net/~rwhron/kernel/lmbench-getsummary.diff
and a script to summarize multiple lmbench runs:

These are all seconds to build a package, or in the case of bonnie, time to
run the benchmark. NFS numbers are missing for 2.5.66*. I believe 2.5.x
needs NFS v3.
