performance got degraded after move to hpux11iv3 from hpux11iv2
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?

Re: performance got degraded after move to hpux11iv3 from hpux11iv2
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)
