Thread: cost per transaction
Hi, all I'm writing the slides for the road2pgday and I'm wondering if there's some test about the cost per transaction that have PostgreSQL on OLTP. If there're please give me the urls where i can find it so I'll include into my presentations :) Best Regards -- Federico Campoli PGDay 2007 Committee :: http://www.pgday.it Scopri il piu' avanzato database Libero

AFAIK, there aren't any audited public benchmarks for PostgreSQL. So, you're not going to find a TPC-C or TPC-E for PostgreSQL yet. There may have been one of the SPEC benchmarks that used PostgreSQL, but that wouldn't have been direct OLTP. Being free, PostgreSQL's cost-per-transaction would be fairly low. Basically, if you purchase maintenance, support, installation, or tuning services from a PostgreSQL support organization or consultant, then you're cost/transaction is really based on that fee and the number of your applications transactions run over the lifetime of the support contract. Unlike other database vendors, there's no cost/transaction for free PostgreSQL. -- Jonah H.

The last time I looked at TP$ benchmarks, they counted the cost of
both software and hardware when accounting for costs.
The fact that PostgreSQL may have no licensing fees might imply that
the *software* cost per transaction is $0. But the hardware still has
some cost, so you will have to count that...
