    We have a machine with a quad core 'Intel(R) Xeon(R) CPU E5-1410 0 @
    2.80GHz' running asterisk 11.2-cert with ingress and egress all sip.
    Fastagi running as a daemon (written in perl) performing cdr updates
    at call start, answer and call end together with a query when a call
    comes in to get information on what to do with it. Local Mysql 5.5
    database.<br>
    With all this we easily handled 450 simultaneous calls with many of
    them also performing call recording. I think we typically had 60%
    idle on each processor so the box could be pushed a lot more.<br>

            How did the system behave with 244 calls? I’ve been able to
            make 1,024 concurrent faxes (which tend to use more
            resources than audio calls) in the lab. The problem I had
            was after the faxes were transmitted, things couldn’t keep
            up and kept dumping core. Two things were going on, (1) the
            CDR was written to MySQL and (2) a FastAGI script (I use the
            AGISpeedy PERL package) to write a log entry also to MySQL.
            I tried switching the CDR’s to sqlite and that seemed able
            to keep up, except that its concurrency issues were a
            problem. If MySQL is the problem, I could probably optimize
            it better, but it doesn’t explain the Asterisk core dumps.
            It might be related to the number of FastAGI scripts
            running, I’m not sure at this point.<o:p></o:p></span></p>
