Hi,

I have performance problems with the postmaster-process. The CPU usage is permanently 
around 90 %.

My DB:

    3,5 GB Size
    largest table ca. 700 000 rows

Most access:

    Finde a row - Update if exist Insert else

Average access:

    10 times a second

    every Query needs ca. 20 ms


All server options are still default !!

Any idea on wich "screw" I can turn ?.


Thanks for suggestions!
