Thanks again.

I have connection pooling which works fine. Also I have created SQLPackages and data compression
to true.

Hi again, 
Few tips : 
Use connection pooling, cache data from database if you can, lazyload data from database when
that is a good idea etc.

Creating connections to DB2 is not the fastest thing around, so I suspect connection pooling
may take 2 seconds of that time. 

Hope it helps
