It's a TPC-B Benchmark and was later modified by Guillaume Smet
(sequoia-list) for having a read-only benchmark. There are three
UPDATEs, one INSERT and one SELECT per transaction and i tried several
settings of 10 or more clients doing one transaction at the same time.

I'm using the hedera jgroup communication like in the distributed demo.

All the PostgreSQL-servers are running on virtualmachines on different
servers and JDBCBench is running on my box.
