Re: PostgreSQL with Zabbix - problem of newbe

<cut>
Hi all.

Well I have used all Your recomendations but I still have no luck with
performance tunning. The machine has a moments thas was utilized in
100%. The problem was I/O on disks. CPU's were busy on system
interrupts.

I have started again to look of I/O performance tunning and I have changed a

synchronous_commit = off

Ofcourse with risk that if there will be a power failure I will lose
some data. But this is acceptable.

This caused a monumental performance jump. From a machine that is
utilized on 100%, machine is now sleeping and doing nothing. I have
executed some sqls on huge tables like history and all has executed
like lightning. Comparing to MySQL, PostgreSQL in this configuration
is about 30 - 40% faster in serving data. Housekeeper is about 2 to 3
times faster!!!!

Many thanks to all helpers and all PostgreSQL team.
