the svn-process never uses more than about 10% of cpu when I checkout over
64kbs-line (5min).

But the cpu seems to be the bottleneck when you use svnserve ovre a 100MB-LAN.

Sorry, but I can't check my mails until next Tuesday.

Thanks for your help. svnserve works great for me. When I'm back I'll try to
find the bottleneck.

Hava a nice week
