Something I forgot to mention was that after we fixed the issue on all of the new Win7 64bit machines all of the older XP machines no longer had similar problems.
The conclusion we have come to is that the global network slowdown was caused by the Win7 machines network traffic with the servers, once there were no Win7 conflicts ALL of the "not responding" issues went away.
At first the culprit was thought to be the integrated Realtek NICs, but different drivers and even Intel NIC cards were only temporary fixes until the fix I mentioned above was tried.
I was going to suggest you see what SAVEFIDELITY was set to...
Switching off the pallette stuff (should have done that in the first place before posting here...) speeds up things considerably! Palette stuff I mean are the layerdialog and the ribbon-hatch and mtext thingy.
No more "not responding" messages switching between drawings or layouts - things work as smooth as with XP.
It's a bit of a shame those things can't be used properly - they CAN speed up work....
When I am on AutoCAD 2011, I am hardly able to move my cursor due to something making my computer run slow. I hasn't always been this way. Revit 2010 is also very slow. It may be because I am working with a larger file but it is very frustrating. Any help would be appreciated!
My system is My system: Windows XP Pro 2002 SP 3
Intel(R) Core (TM)2 Duo CPU
T7250 @2.00GHz, 777MHz, 3.5 GB of RAM
And I have less than 4GB of hard drive space. I wonder if that has anything to do with the slow performance.
Instead of guessing and trying other people's ideas you should take RKMcSwain's advice that he gives out often and download and run the process monitor. You will see in real time what is holding up the program/OS and then you can fix it.
I had similar problems.
It was my McAfee securtiy realtime scanning that was the problem.
If you temporarily switch off the real time scanning when in Autocad everything runs smoothly.
