Actually, this is just to let you know that for _stability_ and performance tests we use the "Network Database Benchmark" which we open-sourced (GPLv2) in 2006. Just recently one of our colleagues wrote a _small_ patch that makes it work out of the box with _PostgreSQL_/UnixODBC. The patch is now also available. The main project page(s): http://hoslab.cs.helsinki.fi/savane/projects/ndbbenchmark/ http://hoslab.cs.helsinki.fi/homepages/ndbbenchmark/ The patch: http://hoslab.cs.helsinki.fi/savane/cookbook/?func=detailitem&item_id=14 1 The benchmark models a Telco home location register (HLR) application with lots of short read/write transactions whose ratio can be adjusted on the command line, e.g. to model read or write heavy transaction loads. We'll re-use this benchmark as we have lots of existing measurements for other databases. Also we have a pretty good understanding of what to expect performance-wise with the different transaction mixes. The actual benchmark specification is available from here The benchmark spec: http://hoslab.cs.helsinki.fi/downloads/ndbbenchmark/Network_Database_Ben chmark_Definition_2006-02-01.pdf Thoralf -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
