Hello,
one of our services is click counting for on line advertising. We do
this by importing Apache log files every five minutes. This results in a
lot of insert and delete statements. At the same time our customers
shall be able to do on line reporting.
We have a box with
Linux Fedora Core 3, Postgres 7.4.2
Intel(R) Pentium(R) 4 CPU 2.40GHz
2 scsi 76GB disks (15.000RPM, 2ms)
I did put pg_xlog on another file system on other discs.
Still when several users are on line the reporting gets very slow.
Queries can take more then 2 min.
I need some ideas how to improve performance in some orders of
magnitude. I already thought of a box with the whole database on a ram
disc. So really any idea is welcome.
Ulrich
