PP server connection optimization settings questions

I have a PP setup on 2 servers, SharePoint/ProductPoint on one and the SQL database on the other. PP version 1.1 M030.

I have Pro/E WF5 installed on a couple machines. On all of them there is a large wait time when Pro/E is launched. I have 3 test machines, 2 are 32bit machines and one is 64bit. The 32bit machines are Windows XP and Vista while the 64bit machine is Windows 7. All act the same when it comes to the connection of Pro/E to PP. The Win7 machine also has a 1GB network connection. The Pro/E version in 5.0 M050.

Both of the servers are hosted locally here at my site in the same server room.

When Pro/E is launched some times it comes up fast and other times it is unresponsive for some length of time. Then, when you try to open a part you get large delays between when you click open and the dialog is ready. Then, again everytime you click on a new part or change the type to assembly for example. It does not seem to much difference if the preview window is open or not. Once I have selected a part/assembly in the open dialog it will switch back to it quickly. It is just slow the first time going to it. This makes it hard to look for a specific part, especially if you want to see the preview to help know if the part is right.

I need PP point to respond my quicker.

Does anyone know any tips or tricks for optimizing the client/server connection?
