RE: JDBC Performance

Doesn't sound normal! Can you post the schema for the table you are
updating

 pg_dump -s -t tablename dbname

One thing you can try if you are doing bulk updates is to drop the index
before the update, and create it again afterwards

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?

TIP 2: you can get off all lists at once with the unregister command
    (send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
