Very true.

Which is why, at least in the 2.X version of Webalizer, you can do 
something special where you run webalizer twice, once to have it parse 
the log files and do the DNS lookups, outputting to a special webalizer 
DNS cache file, and once to have it actually parse the log files and 
generate the stats, using the webalizer DNS cache file.

For more details, check out the webalizer website.

Of course, this concentrates the lookups all at one time, which may be 
problematic on servers that don't have a lot of memory, but it prevents 
the ongoing, all-the-time apache slowdown of doing the ReverseDNS in 
apache.conf.
