This is very interesting! Giovanni, do you mean that FS reads once the target of the “hold_music” variable? Or specifically “local_stream://moh” as an argument to local_stream? I’ll update the wiki with this useful info. Thanks. --- John Boteler BnC Group U.S.A.

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) -giovanni 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.

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.
