Yesterday, I tried it with the KDE repository (>723k revisions) under x64.
My results:

* load cache & query data : ~ 2s, 150MB
* pass data to log dialog : ~60s, 1130MB (1.3G total)
* fill grid (auto-colwith?): ~75s, <20MB
* sort grid : ~85s

* open statistics: ~10s

So, there is definitely room for improvement in TSVN 1.6 because you begin
to notice the data transfer and the grid effect even with a few thousand
revs.
(By comparison, the revision graph takes less than 1 second for the query
and 10 secs to draw the >700k nodes).

I ran out of UI resources (pen / brush handles?) in "Commits by date"
with a threshold of 0 (i.e. 1700 users) and "Stacked Line Graph" when
I moved the mouse over it. To reproduce it, you may try to create
a simple repository with ~10000 commits and give every commit a
different user and / or date.
