Just a quick note to say, I *finally* got my SA working faster by adding PTR records for the MySQL server.
*grin*.. never underestimate the importance of having PTR records, or hosts file entries, for all of your machines.
A lot of services have support for access-restriction by hostname, thus have to RNDS all incoming connections..
Other apps (mostly LAN scale apps) will just RDNS them for logging purposes. This isn't much of a problem, since all hosts on the local lan should always have a valid PTR unless they are bogons.
Either way, an app that has to keep timing out RDNS operations is going to be painfully slow.
