"limit status scans to affected paths" - ok, try to understand here:
fetching the status of a single path is very expensive (see 'bug' report
above). Imagine you did an update/commit of 100 files, your working copy
consists of 10000 files in 100 folders. Fetching the status for those
100 files would be the same as fetching the status for the whole working
copy. (assuming all 100 folders have the same amount of files in them).

I don't know how you're working in your project. But it really seems you
should better change your project a little.
If you need to lock a file so you can merge/resolve conflicts/commit
without anyone else committing in the mean time, then maybe you should
try to improve the communication in your team. Several people working on
the very same files at the same time usually means destroying each
others work, or the files contain too much functions/methods/classes and
require splitting up into several files.
If you however lock a file after an update, you're locking the file
while you are working on it until you commit that change. That's much
better than your approach "I'm finished, now everybody hold still until
I clean up the mess from others (i.e. resolving conflicts) and could commit"

You told earlier that your working copy is about 16GB, 190000 files,
90000 folders. If that working copy takes you 15 to 45 minutes, you
either have a harddrive from the last century or your working copy
resides on a network share and not your local harddrive. I can't believe
that on a normal local harddrive it would take that much time for a
If you really have your working copy on a network share, then I suggest
to change that instead of implementing ugly hacks into TSVN.

Select the files you want to commit, right-click, choose "commit".
