Here are a few options you may want to try. These variables do depend on your architecture and may require tweaking.

Sorry for lack of attention! Watching a rare game (blue jays vs red sox and jays are actually winning!) Please have your systems team check the environment for taks/jobs scheduled during that time or any new changes to the infrastructure.

I'm not saying its not possible but i think it's not the app. It could be the environment. Can you please provide: if the slowness is consistent during a particular time during the day? Is it always the case? What about Afterhours? Does the slowness also happen during Afterhours? <--- key since that's how I found my issue! example: the systems team is testing a new back up system or daily network job/task of some sort. I see your on Sp3, when was SP3 applied? Or was it from a fresh install that included SP3?

In that case, and since you mentioned everything is OK when rebooting the mid-tier, it could be, like Ravi mentioned, the pre-load setting. Usually, I turn that off once the mid tier has been up for a few days. Also, you could check to see in the java settings on the mid tier, to see if you have the following garbage collection related settings enabled. This could lead to some stability for you. -XX:+UseCompressedOops -XX:+UseConcMarkSweepGC On Fri, Jul 20, 2012 at 5:33 PM, ravi rai <ravira...@hotmail.com> wrote: ** How many App server you have and how many Mid tier serves? Running FTS and all operation on a single box might cause that as FTS is very heavy You can also check Tomcat settings related to HTTP-keep Alive , max and min memory, Heap size etc Refere 7.6 Performance tuning for BSM.pdf check your defination check interval, pre Load , Prefetch setting, caching on Mid tier might be causing it.
