You can’t do what I suggested with *mod_php*…since *apache* will only load one *mod_php* at a time.
If you use *nginx*, *php_fpm* is the only game in town (besides the uber-slow CGI). *php_fpm* works with *nginx* too…not so with *mod_php*.
*php_fpm* is multithreaded too…and gives you the ability to assign different PHP requests to different thread pools based on **mpm_worker* & *mpm_event* use multiple threads (and only a few processes).Īs far as future-proofing goes, *mod_php*’s days are numbered. Since *mpm_prefork* uses multiple processes to handle requests, it requires the most system resources. *mod_php* is not thread-safe so you can only use it with *mpm_prefork*. The reasons for using *php-fpm* is to future-proof your installation and thread-safety. Is there any advantage to running FPM vs. One is the EspoCRM database that is only used by me. My sites are small and get very little traffic. Imagine what your performance would be like if you had to unload mod_php, load a different mod_php & reload apache for every single request!ĭescription > Let me ask this.

This will save a lot of (what may be left of) your hair. Unless your picture gallery uses some really obtuse features or relies on something equally obtuse that was deprecated in 8.0, my guess is that it will probably work - the differences are pretty minor.
