We are experiencing critical issues with using FreePBX in a large installation (over 1000 extensions). We have a server with 8 cores and 16 GB of RAM, however the graphical interface is extremely slow. We do not notice a saturation in the use of server resources (CPU load and memory usage is very low). The IO rate (disk and network) is also low. However the interface is very slow (especially the dashboard - config.php?display=index). In another thread we verified that it could be DNS problem, but we tested and the DNS is accessible from the machine (latency of 0.2ms). Any idea what could be causing such extreme slowness?
We noticed that the communication between FreePBX and asterisk (version 14.7.5) is very slow. Simple actions such as retrieving asterisk information (admin page / admin/config.php?display=asteriskinfo) have taken more than 30 seconds. I think the main problem might be exactly the response time of the communication between freepbx and asterisk.
Our installation is working in dual stack (ipv4 and ipv6). Most extensions are in ipv6 + TLS. We have not had a problem in communication (calls), but in using the FreePBX graphical interface.
