Any update on this? We've had the same issue for some time now. We are currently on version 3.0.5 of CodeRush and Refactor. If I go into Add-In Manager and disable Develper Express Tools the solutions become incredibly responsive in comparison. Here's what I see:
VS2005
In loading the solution - it is always noticably slower 60 seconds vs 10 seconds
The UI occasionally just goes out to lunch for 1 to 120 seconds. Especially when clicking to move the insertion point.
VS2008
The issue is not as extreme, but not gone.
Seems to happen on EVERY large solution. We're all running dual-core P-4s with 2 or 4GB RAM. I've not paid attention to memory consumption, but CPU goes through the roof while it's "thinking".

PS : I made a 27MB WMV file showing the issue and how it completely goes away after the tools are turned off. It shows VS2008, a clock with a sweep hand and task manager showing the CPU usage and how it eats up twice as much RAM before coming back to life. I don't know if this will hep you. Also, one of our guys says that he's now running VS inside a virtual machine (allocated 2GB RAM) and the problem does not show up - even though he previously had the issue on his host OS. I'm going to try that and let you know...
