annotations, blocks and dims = slow drawing?

Has anyone noticed a substantial performance loss when adding a lot
of either blocks, annotations or dimensions to a drawing? We have a
drawing that when first created performed very well but now that we
have it fully populated with blocks, annotations and dimensions it has
slowed dramatically.

Thanks, Sam

 

Interesting observation. These entities all require line elements. And
line elements have always exacted a big toll on SW.So it doesn't
surprise me one bit. I'll see if I can quantify this.
