Slow AutoCAD startup or performance

Here are some tips that might help.

Generally with antivirus software's try to disable them if you find that AutoCAD performance is slow typically during start as well as opening and saving of files. If it seems like it is the antivirus software that is the cause try to make exceptions for for example the install folders of AutoCAD, specific file types like DWG,AC$, SV$. Set to scan for write operations only for acad.exe should be safe.

If changing annotation scale in a viewport takes long time try resetting the scale list in  the drawing and its xrefs. Make sure to reset the scale from the bottom of the xref tree, one drawing at a time and last in the host drawing.

Knowledge Base documents worth looking at:

Outside The Box also has a tip to disable the AutoCAD InfoCenter. It's related to seeing these dialog boxes and started after applying SP1.
