Hi David,

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.

Were you using the call centre module in your test? If so, I'd suggest moving it to an external RDBMS such as PGSQL (could be running on the same VM).

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.

Similar issue here: https://lists.freeswitch.org/pipermail/freeswitch-users/2012-October/088895.html

Thanks,
Shaun

BTW sqlite is on a ram disk.

Hello all,

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

I'm just running test calls, fs receives and playback a wav file. This is at 700 channels.
