Thanks for replying. I’m not using mod_callcenter at all. I’m simply playing back a file. I wonder if this is cpu bounding. I guess I can test this by doing echo instead.
to eliminate cpu load from reading/decoding file, use moh (read just one time, then broadcast samples to all calls, no cpu, I believe less than echo in case of many concurrent calls)

I also added another profile, since I read on a thread it might help (also read that’s not true), but that’s not it. All of my metal boxes work just fine at ~3000 channels, so I’m thinking it’s related somehow to the underlying VM.Thanks again.--On Wed, 14 Oct 2020 at 07:29, Shaun Stokes <shaun@sysconfig.cloud> wrote:
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.

Subject: Re: [Freeswitch-users] FS on a VM only uses one cpu?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.
