Hi JJ,

I used one of the win32 box with collabnet subversion 1.5.0 binary and tested your scenario.

I did not observe any slowness.

Let me try with VS2008 built svn 1.5.0 and see how it fares!

With regards
Kamesh Jayachandran

Kamesh,

It's been a while since I followed up on this thread.

Did you get the branch-neon.log file I sent you back in June? If not, you
can get it from http://svn.haxx.se/users/archive-2008-06/1088.shtml. Your
email was bouncing every time I tried to resend it.

Have you found anything else related to this? Are there any other plans for
improving Windows merge performance? I also read
http://svn.haxx.se/dev/archive-2008-06/0628.shtml, which I assume is
related.

Thanks,
JJ
