Hello,
We've recently migrated our existing MODX Revo 2.5 website to a new server. The old server was RHEL 6.x; the new one is RHEL 7 (apache on both). The installation went fine; however, the site is noticeably slower to load on the new server than the old one, despite better, faster hardware.
I haven't found any pages describing RHEL/CentOS 7 performance tuning. However, there's one difference from our old RHEL 6 server that I suspect may be causing some of this, which is that the old site had mod_fastcgi, but I don't believe it's possible to install mod_fastcgi on RHEL 7 (see, for example,
http://serverfault.com/questions/629937/centos-7-apache2-httpd-mod-fastcgi-installation-impossible). The replacement for mod_fastcgi is supposed to be mod_proxy_fcgi; however, I don't know how to configure or use it with MODX.
So my questions are:
1. Is the lack of fastcgi a likely culprit for the performance issues we're seeing?
2. If yes, can anyone point me at instructions for using modx_proxy_fcgi, or some other recommended replacement for mod_fastcgi, with MODX on RHEL/CentOS 7?
3. Are there any MODX performance tuning instructions that address RHEL/CentOS 7?
Thank you SO much in advance for your help!
