Re: JT400/JDBC performance issues

Suresh,

To get performance that bad it seems like it would have to have something
to do with the JDBC statements you are executing.  Are you using SQL Views
in your SELECT?  Generally, these perform worse than Tables on the iSeries.

You do not mention how large your tables are or how many records you are
selecting.

Finally, once those issues are worked out, a big area where problems will
occur with the iSeries is if you do not use Connection Pools.  Establishing
a connection to the iSeries has a high overhead.  Using a pool eliminates
that problem.  However, we are talking seconds not minutes.

Hope this helps,

Mark
