What a difference a few bytes can make. And what a great community this is. I received a number of responses to yesterday’s Mystery of the Plodding HTTP Requests, but the one that nailed it was Greg Barnett’s (resume) suggestion that I check to make sure HostnameLookups are set to off in httpd.conf. With that tiny tweak, every Mac on campus can access our site as fast as our Windows boxes can. Oddly, the fix works for both OS 9 and OS X Macs, so whatever it is that causes hostname lookups to work differently on Mac OS than on Windows stretches across Mac OS versions. It’s a strange universe we live in.
