If you think this is bad then you weren't around in the days when we used sup. :-) Tagging makes everybody's updates take longer, and as a result the server's client counts go up. CVSup7 has a limit of 20, and I can tell you that machine is breathing pretty hard. But it seems to be performing quite well given the load. This is the first time I've ever seen it max out. Other than the increased load because of the number of clients, the bottleneck usually isn't in the server when the tree is tagged. The bottleneck is almost always your hard drive in that case, since it has to edit every file in your repository, write the edited version to a temp file, check the MD5 signature, and then move the temp file to the right place again.
