Hi
After upgrading DBI and DBD::Pg, this benchmark still picks MySQL as the winner (at least on Linux
RH3 on a Dell 1875 server with 2 hyperthreaded 3.6GHz CPUs and 4GB RAM).
I've applied the following parameters to postgres.conf:
max_connections = 500
shared_buffers = 3000
work_mem = 100000
effective_cache_size = 3000000000
Most queries still perform slower than with MySQL.
Is there anything else that can be tweaked or is this a limitation of PG or the benchmark?
Thanks.
