Does anyone know of a good way to speed up PHP on IIS6? I'm running 5.2.6 as ISAPI, and I have a WordPress installation that I'd like to speed up (not the front end, which I'm planning on caching anyways, but the backend CMS -- it's still too slow for my taste). I've tried installing Zend Optimizer 3.3.3, but could not for the life of me get it to work. I'm looking into eAccelerator next. I also looked at APC for a second, but now I don't remember why I didn't go much further down that path. Maybe I'll revisit that too. But before I spend any more time trying to get another one to work, it would be great to hear from someone who's had good experience with one before. Stephen, perhaps you have a recommendation or have some experience with something? I'd really appreciate the insight! Thanks.
