That still sounds like the networking is involved though. That said,
I do not see why other commands would not show the same.

Are you interested in seeing my timings for the same commands? I am
in the process of installing the latest versions so I can test. On
Linux, this is what I got though:

$ time svn merge --dry-run --accept postpone -r11761:11762

real 0m9.895s
user 0m1.539s
sys 0m0.416s

I did that from a box inside the CollabNet network though, so it was
essentially contacting Tigris via the LAN.
