Hi All,
 
I have a postgres SQL Table which contains 30 Million Records. It is a simple flat table with 4 columns. Each column has an index and I select from this table using a single column at any time.
 
Here's the problem. A simple select statement takes upto 30 seconds to respond, if I add in connection pooling and 15 - 20 concurrent requests the responses are now 15-20 minutes!! I have no idea what the tuning options may be, but I need to get these queries running in 30 seconds or so.
 
Any ideas?
 
Regards,
Dean.
