Hi Shelby,
Thanks! That's pretty useful. I also note that this same info is
available from the CLI, although I was curious as to what some of the
numbers indicated:
UP 0 years, 13 days, 19 hours, 25 minutes, 48 seconds, 887 milliseconds, 975 microseconds
529509 session(s) since startup
26 session(s) 0/30
1000 session(s) max
Specifically, 26 sessions 0/30... I take it this means there are 26
current sessions, but I'm unsure of what the "0/30" means.

Try using xml_rpc ... status or show channels will give you what you need.

people using to analyze their CDR's to discover this? I'm handling
about 30k calls per day but have only a bandwidth-based guesstimate of
the peak number of concurrent calls I'm handling.
If there's an open source solution, I'd appreciate a pointer.
Regards,

server from FS with FS on a Dell R710 with their current best
processor option (Intel Xeon X5570 @2.93GHz with 8-cores total) and 32
GB memory. The web app server is less than half the power of the R710.
I maxed the web app server at 300 calls per second (both setting up
and tearing down) and the R710 running FS was 65% idle. No audio was
being proxied through FS, though. If I were running the web app server
on an equivalent R710, they probably would have been on-par with each
other in performance. Extrapolating, I expect that in such a case I
should be able to get at least 650 CPS out of FS, though for
production I would probably limit it to 400 CPS or less so I leave
room for miscellaneous tasks. I maxed out the R710 at over 16,000
simultaneous calls (again, no audio proxying) but the only reason I
couldn't do more was because I hit some sort of thread creation limit
in Linux. There was about 17 GB of memory used for this many calls.
This should give you some ballpark idea of what you can accomplish
with FS.
At some point, I will track down and resolve the thread creation
issue, at which time I believe call limits will be limited either by a
complex combination of available memory, the speed of the processor,
the cost of thread context switching, calls per second setup rate, and
call duration.

Please remember NO benchmarks are endorsed by the FS community or
developers, because there are just too many variables, and a simple
figure is just useful for marketing hype, not for real dimensioning.
You MUST do your own benchmarking, so you get an idea about how to
dimension for your own use case and hardware.
