Hi all,
I have a table which has more than 10millions records in pgsql which is running on window 2003. During night, nobody search the database. In morning, when people start to the application, it will take more than 30 seconds to get database back. After several times of same searching, the results can be returned in 8 seconds. Is this related to some kinds of process priority setting in window 2003? If so, how do I set the pgsql processes in highest priority?

are there other applications running on this same server? my first guess is, other programs are doing disk IO when the postgres database is idle, and pushing the postgres stuff out of the in-memory cache. Windows is pretty aggressive about reclaiming idle memory, and there's not much you can do about it.

maybe schedule something to run in the AM shortly before the regular database users show up which will do queries that force a full table scan on each table, this will cause all the imporant data to swap back in.
