Re: Slow Query Performance from the Web

How big is the result set that is being passed back to Websphere from the
iSeries?  If it is a large result set and it is ALL being passed back that
could be a potential problem. What Java tooling are you using (i.e. Struts,
JSF, Tapestry??), sometimes you have to watch how long those frameworks hold
on to result sets.

Are you using an ORM solution in your Java (i.e. Hibernate)?  There are many
ways to optimize such tools (i.e. lazy loading, caching, etc.)

Subject: [WEB400] Slow Query Performance from the Web

Hi All, 
 
 I'm new to this list - and I'm not sure this is the proper place to be
asking this question - but I'd appreciate any direction you can give. 
 
We have a query that runs over a view that joins together several related
physical files. We created indexes for each physical based on the Where
clause in the query and when I run it through STRSQL on the
400 - the performance is good - about 8-9 seconds.   When the same query
is passed from the web - we're running websphere on Window 2003 boxes - it
takes in the neighborhood of 1 minute 10 seconds.  
 
  We are trying to figure out what can be done to optimize it from the web.
I realize I'm probably not giving enough information here - I just have no
clue where to start!  If any of you have any ideas I'd be eternally
grateful.
 
Thanks
