Thread: JDBC Performance

I am having some performance problems with postgresql and JDBC when it
comes to updates.  If I try and update a record it seems to be taking 1.7
seconds for 100 records or 14 seconds for 500 records.  An insert is only
taking between 3-5 ms/record.  Performance on the updates continue to
decrease until I vacuum analyze the database again.  Is this normal?
