Thanks for this. One of the servers is using sata and the other scsii drives, so that may be the problem, I'll give it a go. Problem seems to escalate past 200 active calls. Below that all is well.
That said, it could also be a db issue, so I've changed my log tables to innodb (I'm hoping that now I have row level locking as opposed to table level it will help) Regards, ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Anthony Minessale Sent: 16 April 2009 23:25 To: [email protected] Subject: Re: [Freeswitch-users] Optimum sound file format Looking at your post, You are already using the best format. If you do not have a fast filesystem try making a ram disk and play the files from there instead. if you *really* want you can use sox to turn them all into raw alaw files and rename them with a .PCMA extension to avoid the g711 transconding but g711 to PCM is pretty trivial. it's more likely a file i/o distress you see.

I've found CPU load increases rapidly with the number of threads playing a .wav file. Can anyone tell me the optimum when using g711a? Right now the the .wav files are Audio format: PCM Sample rate : 8 kHz Mono Sample Size: 16 bit Bit rate :128kbps Will it help CPU load if I resample to a bit rate of 64kbps and sample size of 8 bit? I have read that the sample size needs to be 13-14bit +1 for alaw/ulaw though Regards, _______________________________________________ Freeswitch-users mailing list [email protected] http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org -- Anthony Minessale II FreeSWITCH http://www.freeswitch.org/ ClueCon http://www.cluecon.com/ AIM: anthm MSN:[email protected] <mailto:msn%[email protected]> GTALK/JABBER/PAYPAL:[email protected] <mailto:paypal%[email protected]> IRC: irc.freenode.net #freeswitch FreeSWITCH Developer Conference sip:[email protected] <mailto:sip%[email protected]> iax:[email protected]/888 googletalk:[email protected] <mailto:googletalk%3aconf%[email protected]> pstn:213-799-1400
