This is a tiny change which should improve Hunchentoot's performance. Incidentally, if you're concerned about performance, you might consider giving FLEXI-STREAMS 0.15.0 a try which was also released today. http://weitz.de/files/hunchentoot.tar.gz http://weitz.de/files/flexi-streams.tar.gz I'd also recommend to everyone interested in Hunchentoot's future directions to check out Hans' current version from here http://trac.common-lisp.net/tbnl/browser/branches/hans and to play with it. This version needs an updated Chunga (at least 0.4.2): http://weitz.de/files/chunga.tar.gz Edi.
