My working copy of the TSVN source has 4966 folders with 4.92GB data.

First, check *what* exactly takes so much time. In the update progress
dialog, what does require so much time? Is it before the first items get
updated or do the updated items themselves show up slow? (i.e., time
until it 'starts' or time while update is in progress).

If it's the second, then the problem is your connection speed to the
repository.

If it's the first, then the problem is disk access of the working copy.
There are several things that can cause a slowdown of disk access. The
most obvious if you have your working copy not on a local harddrive but
a network share (in that case you shouldn't even be surprised by the
slowdown and re-think your setup).
Other factors that slow down harddrive access:
* virus scanners (exclude the working copies from getting scanned)
* desktop search engines (not so much a problem on Vista anymore due to
improved APIs for such engines)
* slow harddrive
