After upgrading to 10.1.500.16 we now have large delays at the UI

We upgraded to V10.1.500.16. Our system was very responsive and working well until we upgraded.
Now we are seeing large delays that come and go. One minute I will preview a Sales Order and it will take 90seconds for the form to preview (or even start a new Sales Order will have the same issue). The next time I try to preview a Sales Order or create a new Sales Order it will take only 5 seconds (approx.).

However, it comes and goes.

We did NOT upgrade the system task agent. We upgraded from 10.1.500.11 so it was not a huge jump.

Anyone see anything like this?

Thanks,

That almost sounds like your app pool is recycling. Are you monitoring the app pool? Turn on log in IIS app pool and look at Windows Event Viewer. Alternatively have the Epicor Trace enabled and watch for initialization which means the same thing - new app pool instance.

Thank you Mr. Bart: I will give that a try.
