First of all Thank for you answer

I give you more information---
we have migrated to 5.5 last weeked from 5.0 on a teorichally more powerfull architecture, but we are registering a performance problem during import XML from external system, via glog.integration.servlet.WMServlet.
We are investigating on this issue, looking at DB tuning (we had still tuned it with new statistics and so on during our integration test..but seem that some specific query on 5.5 db are worst respect 5.0 db), but in the meantime I want to isolate and separate INTEGRATION activity from USER activity and if possible also from RECURRING PROCESS Activity, because this extra time consumed in integration seems affect also normal UI activity.

Perhaps it's not only a DB problem, could be also a performance problem on App Server ..condiring that we moving out from a BEA old and stable to a new (And not so tested...) OAS

Thanks in advance for any kind of suggestions

Ciao
