We have started to deploy AutoCAD 2011 64 Bit on Windows 7 64 Bit machines and have come across an issue where when opening or saving files across a Cisco WAAS accelerated network that have referenced images takes a lot more time than drawings that do not have attached images. We have updated graphics drivers to the most recent certified driver from the autodesk site as well as disabling Aero and all the other Windows 7 tweaks to no avail. The files with images still open/save mush slower than those without. Has anyone else experienced this or have any insight to what we can do to resolve this issue?
We were actually able to resolve the issue by re-installing AutoCAD 2011. Not sure what the issue was but process monitor would show AutoCAD getting hung up trying to load some external library during the process. Unfortunately, I don't remember what the dll file it was trying to load was.
