I've switched a few low usage servers to EasyApache4 and using PHP-FPM. Mostly I've used a combination of the documentation at https://documentation.cpanel.net/display/CKB/Configure+PHP-FPM+with+User+Pools+for+EasyApache+4 and instructions in the thread and post at PHP-FPM Directory Index index.html file not found problem So far, everything looks to be working pretty good. No issues that I am aware of, but again these are very low use servers with very few accounts on them. How well does PHP-FPM, specifically the method described in the above links, work on servers with 300, 500, or 700 accounts? I have slight reservations that the user pools will scale that high. Thoughts?
