me too I tried it: I forbidden Mathematica to accessin Internet (Help-
>Internet Connectivity) and the slowdowns remained the same.

I'd like very much to know what kind of Java code is needed right from
the start in the Doc center, and in particular in the Virtual Book and
the Function Navigator - since these last two are noticeably even
slower.
