Anyone knows the problem that the drawing is slower when you used annotative text.

It shouldn't have any affect.  There must be something else going on.Upload a copy of the drawing in question so we can have a look at it.

I have on this momment no drawing with annotative text. In the past I have had problems. i would like to try it again but would like to know whether this is a known issue.

To my knowledge it is NOT a known issue.
