I created the benchmark and ran it on my work laptop today.  The
results are at http://docs.google.com/View?id=dd5f3337_13hbmxpjhj

In summary, I was able to get fairly consistently, update rates of
25-30,000 updates per second along with 250-300,000 reads per second
with eight concurrent processes working in parallel on the problem on
a dual core laptop with 4GB RAM on a jfs file system on a 200GB
7,200rpm SATA drive using GT.M V5.3-004A on Kubuntu 9.10.  I ran the
database with "before image journaling" which provides for backward
recovery (i.e., in place recovery of the database from the journal
without the need to restore a backup).

I did not spend much time tuning database parameters to maximize
throughput.  That's a task for another day.

Questions about how the program works are welcome as are questions and
comments on the results.

Regards
-- Bhaskar
