Pro/E WF5 Performance with PDMLink slower than WF3

All,

We are currently using WF3/m240 with PDMLink 9.1/m40.

We are working on upgrade to WF5/m90. In our testing, WF5 is slower
interacting with PDMLink versus WF3 in just about everything we're measuring.

We are using IE8 as the browser, as we are having issues getting the Mozilla/Gecko
browser to work (it disappears).

We are working on reviewing the config, client registry and server side settings,
but am wondering if this is something that is a known issue with WF5 and if I'm
fighting a losing battle.

Thanks!

Tom Hogan
