Subject: [ADMIN] how test postgresql.conf settings?
Hi all,
I'm testing different configurations
of postgresql 8.1 running on
debian. The method I was following
was:
- change the postgresql.conf
- restart
postgres (/etc/init.d/postgresql restart )
- execute my test
queries
I have noticed that this is not enough to flush the cache,
I don't
know where it is, if at the raid controller, at OS or at
postgresql
itself. Reboot the machine I don't think it's a good solution
because it
takes quite long. Do you have any suggestion? BTW is there any
tool to
stress the DB, I mean, create a set of queries to execute and throw
a
configurable set of concurrent connections to check the
performance?
Thanks to
all
