my website is currently running in a shared hosting environment with php 7.0 (mod_php) without any problems. I can freely choose between mod_php 7 and various fast cgi/fpm variants. I asked my hoster but did not get some practical information about it, and even google does not help a lot here.
And thats why i'm here to ask: which is better in therms of performance and security? I compared them with help of my website and it seems the fast cgi implementation is slightly faster, but that can also be some sort of measuring inaccuracy. Are there any downsides with it?
