DEMdev Thanks for the reply. Sorry it took awhile to respond.
So I get what your saying about the DEM. Yes...I am persisting maybe a bit too much and GP logon times are yielding that. However, my real problem is with Shell Load times and I have no idea why. The following is what I observed this morning (this is not the 4 minute logon capture as I don't have the new image with logging monitor set to all pools yet).

It does not happen to everyone. It is not pool specific. They all use the same snapshot of the master.
