After we move Informatica from a hpux 11iv2 to hpux1v3 on the same rx4640 server, the system is getting slow, by checking Glance, it seems CPU and Memory util all look ok.
I am wondering if there is any tune steps we usually should perform after we migrate to hpux11iv3 from v2?

one common change between 11iv2 and 11iv3 is the how load balancing works in the IO stack... 11iv3 defaults to a round robin load balancing mechanism that may not work well for some disk arrays when doing sequential io. So questions are - what sort of storage do you have? And is your io sequential? (I'm guessing it is as informatica is an ETL tool)
