On average we process a JSP page in 300 ms, country wide and have approximately 300 tables with over 3 000 000 records in the PostgresQL DB. I would recommend that you look at any Linux distro that supports 64 Bit architecture... ...32 bit machines just don't cope so well. :) Initially we running this off a Win 2000 server running MS-SQL but we could only support 20 concurrent connections... ...if we were lucky. I then converted the DB to PostgresQL and moved this to a Dual PIV running Linux and managed to push the concurrent connections up to 50. We now can support more then 300 concurrent connections and the server keeps smiling. The machine is a quad processor with 8GB of RAM which does not really compare with the PIV as it is in a league of its own, but if you look at the query response and page response on a case-by-case basis, you will see that the 64 bit architecture is normally 2 to 3 times faster then a 32 bit machine.
