A few things to note. First, I'm assuming you're using apache with mod_php. On windows, my understanding is that this simply doesn't perform terribly well. You may get better results with IIS+FastCGI (heck, you might try FastCGI with apache to see if that goes better, too). Regardless, Windows and Mac environments tend not to get you your best performance, though. Second, IIRC, APC allows you to preload classes. I'd recommend investigating that option. Third, how many requests are you benching? You need to run a fair number of requests with APC to ensure that the cache gets loaded and that you're actually hitting the cache (one or two requests simply won't do it). You may be already doing this, but you don't indicate that fact in your description. Also, are you using a DB? or any web services? These may also be contributing to the lag you're seeing. I've benched some barebones apps in the past, as has Paul M. Jones, and the fact of the matter is that frameworks tend to be performance hogs, even when serving simple "Hello World" style pages. That said, being able to handle only 1 or 2 requests per second sounds seriously slow, and I know that most apps I've done with ZF perform much better than that... particularly when using good caching strategies and not hitting a DB or web service. -- Matthew Weier O'Phinney Software Architect | [EMAIL PROTECTED] Zend - The PHP Company | http://www.zend.com/
