I tried that earlier today, after importing and tagging the new
linux-2.4.19-pre9 release into svn. The import took over 6 minutes.
The tag (a simple server-side url copy) took just over a minute.

I was quite surprised that the copy took that long:

$ time svn copy file:///home/rcs/SVN/kernel/{base,linux-2.4.19-pre9}

Committed revision 6.

real 1m9.354s
user 0m19.060s
sys 0m1.290s

Even doing a simple "svn up" null operation where the entire wc is
already at the latest version is taking a long time --- about 18
seconds if the entire tree is already in cache, 1 minute 5 seconds
from cold, and strace is showing a lot of write activity inside the wc
for what should be a noop.
