Application Slowness through ACE 4710

Question

We are struggling with an issue where a user can run a report directly from the server but not from ACE loadbalanced url.
Report run via Individual Web server URL’s
The report takes less than 20 minutes (average 15 minutes) to fetch and return the data. This is observed 9 out of 10 times.
Report run via ACE Load Balanced URL
The report keeps on running for more than 20 minutes and never completes. The front end keeps showing report is running.
The data in general when tested directly by running queries against the database (bypassing the platform) completes in 15-18 minutes
The network connectivity for each and every ports involved (Loadbalancer/Servers) have been throulgly checked.
Please advise what is the best way to troubleshoot this issue.
Thx
Ahmad

Has this ever worked before? YES but the issue is Intermittent
Why do you have a low timeout for your sticky configuration? NOT SURE. WILL HAVE TO CHECK WITH APP OWNERS IF WE CAN INCREASE THAT
If you clear the cookies of the browser and turn off some of the servers to test only with one, do you have the same behavior? Will try to perform this test with app owners
In your tests, are you trying to the same type of query to your database? I mean do you see the problem if you try to update/delete/select in the database? No Refresh is pretty quick.
What are the servers? Oracle, SQL server, MS Access? ORAGLE 11G.
Thanks for your help!
