I have installed phplist on a Red Hat Enterprise Linux server and the admin pages are horribly slow, we can’t work with that it’s really really slow. From the clients side everything is good, the pages loads real fast and the login page load like in a tenth of a second. And when I say slow I mean like 40 to 60 seconds before loading a page in the admin side of the app. It’s my first setup of phplist, we had an old version running on an old RHEL6 server and we wanted to get up to date on versions so we decided to start anew with a new RHEL7.9 server and the latest version of everything needed for phplist, but we have that problem and I can’t find what’s wrong, my server ressources aren’t the problem,if I check all ressources (CPU, MEM, Disk, etc…) are under 1% of utilization. I’ve read other threads about the admin pages slow, but I think my problem is not the same as the solutions didn’t work / apply.
My setup :
MySQL server v.5.7.24 (it’s on another server and I’ve check the ressources there too and nothing seems to be a problem)
Any ideas or a way to pinpoint the problem would be really appreciated.
Thank you very much and have a great day !
