[TSVN] revision graph is slow

I am involved in an evaluation of TortoiseSVN for our development group. I
like the revision graph functionality and I expect it to be of great value
to our group. At the same time, I have some concerns, namely:
1) its performance is sometimes painfully slow
2) the revision graph seems to stop at spaces or empty lines in the log
file, so that it can be incomplete.

My questions are 'am I the only one concerned about the revision graph's
performance?' (I have not found similar complaints in the mail archives)
and 'is there anybody in the community who is planning to take action on
improving the revision graph's performance?'

Thanks,
