I noticed our imap servers were generating a lot of A record lookups for their own IP's the other day and just got around to tracking down the source. Seems like they are all being caused by guid_128_generate() - perhaps the lookup could be cached at start up or it could just use make use of the hostname rather than spending the effort to get the IP via gethostbyname() calls. The function is used in a few other places too, so this might help more than just the stats plugin.
nscd and/or host entries mitigate the total time spent on the lookup of course, but it seems unnecessary.
