WordPress 1.5 speed-up
Данило Шеган (Danilo Šegan) just released a new version of php-gettext, which contains some optimizations I made.
As WordPress 1.5 is using this library to provide translated strings in foreign languages (e.g. German for this site), the pages are now generated noticeably faster than before (>6 seconds vs. 0.5 seconds for this homepage). I hope this improvement gets included into WordPress 1.5.1.
