We also use FS on a RAM Disk, it works great with 100's of concurrent calls on all the databases except for the call centre module which quickly becomes CPU bound.</div>

FS is multi-threaded but there are certain processes which FS creates a dedicated child process for (one thread) such as SQLite (one process per database). If you can find out which FS process is using 100% CPU on one thread then you should be able to identify
the bottleneck.</div>

<div>I compiled 1.10 on a debian-buster VM, and from htop it looks it's only utilizing one CPU.<br>
Anyone seen this?</div>
