Nginx Turn on APC but nothing speedup

There's a science to benchmarking so need to play around with your testing tool parameters (concurrency level, requests tested) + your server config settings. And results are web app specific and if it's backed by MySQL database backend, then you're testing also the MySQL performance and not just PHP which can influence your results. But I have no experince with Magento.
