I have an assembly which consist of:

Parts: 832
Assemblies: 129
Top level mates: 801

I have reached a point in my assembly where mates execute veryslowly.
Trying to move or rotate a part, whether mated or not, is extremelyslow.
Zooming and panning works fine.
My VAR suggested that I have too many mates.

Also, when annotations are shown in a part, or when I'm woking on abusy drawing, trying to move, pan or rotate is extremely slow.

Any suggestions?
