Hi,I have a postgresql database (8.4) running in production whose performance is degrading.
There is no single query that underperforms, all queries do.Another interesting point is that a generic performance test (https://launchpad.net/tpc-b) gives mediocre peformance when run on the database, BUT the same test on a newly created database, on the same pg cluster, on the same tablespace, does perform good.
So the problem seems to be limited to this database, even on newly created tables...
What should I check to find the culprit of this degrading performance ? Franck
