Does it make sense to switch from Apache + mod_php + nginx to nginx + php-fpm?

Question

PHP

there is a VPS server 2core/2GHZ/512mb with Apache with PHP as an Apache module and nginx to return statics, this config serves a PHP site with 6000+ uniques per day. There are still enough resources, but I want it to be more economical and faster. Should I bother with nginx + php-fpm? Judging by the benchmarks, the growth is not strong, plus you will have to fool around with rewrites, htaccess now has a page and a half of rewrites. Pages are now generated in 0.5-1.5 seconds and most of them are probably queries to the database, of which there are 5-10 per page. XCache is used as a PHP accelerator. Is the game worth the candle?

Answer 1

That's when the resources cease to be enough - then the increase will be visible to the naked eye.

Answer 2

There's a meaning. Even if there is no performance gain, at least the entire configuration will become simpler and prettier. Apache is clearly an extra link.
