Running webalizer doesn't seem to take that much machine power etc as long as
the machine has enough RAM etc. When webalizer is using an amount of memory
that approaches the system RAM then things get pretty bad (it's memory
accesses seem quite random/linear and it thrashes totally). When you do a
first-pass to do the DNS (or turn off DNS) things can go fairly quickly.
I haven't had a chance to test my method on 15K vhosts though...

The problem with that comes when you have multiple web server machines.
I set things up with logging to a single file. Then for multiple machines
it's easy to use ssh to get the logs from each machine and merge them into a
single log file.
