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.
