Solved: FreePBX 14 SLOW

I just created a new VM (Hyper-V I admit) running FreePBX 14. It was unusably slow. FreePBX 13 works like a champ. It was a clean install using the FreePBX Distro. TOP didn’t show anything using up the CPU…

On any virtual machines, the bottleneck is usually the hard drive. How many VMs are on this one server? If this is on 2012, you might want to look at your Performance Monitor, in particular the disk usage stats. On my hyper-v server, I’ve got two smaller SSDs joined together, and run 4 virtual machines at once with no performance issues.

The problem was actually the PBX couldn’t reach the DNS server. So this was a configuration fault of my own!
