[asterisk-users] Asterisk scalability
Hello, I wonder how Asterisk scales when we increment the Core's or CPU's of one computer. I see that Asterisk is only one process (I guess that it uses threads). But because Asterisk is only one process, this process is always executed in the same CPU. So we can have a 8 Cores server, with one Core running Asterisk, another Core running operating system stuff/other small daemons and 6 idle cores. Is this correct? Why not? If this is correct, increasing CPU number of Asterisk server box would not increase the performance. I don't see any other process that could use other Cores (like transcoding processes, executing dialplan, etc.) Thank you for your information, -- Carles Pina i EstanyGPG id: 0x8CBDAE64 http://pinux.info Manresa - Barcelona ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Because it is multi-threaded it can run on multiple cores/CPU's at a time. I don't know the internals of Asterisk that well so I can't site specific examples, but I know that there are some scalability bottlenecks people are looking at, specifically with the IAX protocol and how the threads send/receive packets. I'm sure that an Asterisk developer can chime in and give several examples of how Asterisk uses its threads to increase scalability.

I have searched a bit on the Wiki and mailing list archives, but didnt see direct information regarding my scenario: 1. Asterisk for IVR/Voicemail ONLY (no PSTN, no MOH) 2. BudgeTone IP phones and HandyTone 286 ATAs 3. SIP only - separate Proxy+Registrar+CallRouter on other servers 4. G.711u codec, dtmfmode=rfc2883 5. No NAT/firewall (private ethernet network) What I'm looking for is scalability factors: 1. concurrent users accessing IVR and retrieving VM 2. concurrent mailboxes receiving VM (greeting playback, recording a msg) 3. impact of using configuration files vs. postgres vs. mysql Considering these specs for the Asterisk server, will adjust in accordance with scalability forecast: RHEL3 on single Xeon 3.2GHz, 4GB RAM Does anyone have general statistics/findings? Much appreciated! My apologies if this info is already out there somewhere in the archives. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] Asterisk scalability?
Hi Roy- I've done a lot of load testing with asterisk and TE410P's. My guess, with no transcoding, is that you might be able to handle 8 E1's max on the PSTN side absolute max (ie: 2 TE410P's). This assumes you have a fast processor.If you're using T1's, scale these numbers up accordingly, as there are fewer channels per span. Sorry. I tried to say I was to use * as a SIP/IAX gateway in front of a bunch of IAX/PSTN gateways. How many concurrent calls would you think the SIP/IAX gateway can handle? Still, we're talking G.711 and no transcoding, so it's only gatewaying the shite. thanks roy ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [Asterisk-Users] Asterisk scalability?
Hi, Scott Thanks for your information. I have worse luck in load testing with asterisk. I have tried both SIP and H323 inbound calls and terminating on PSTN PRIs. I am using a single Xeon 2.8G chip and 512M Ram and in both cases, once it gets more than a T1, call quality starts to degrade with choppiness, and Asterisk becomes very unstable and resets itself like every 5-15 minutes. Can you let me know more about your tests, like which version of Asterisk are you using for the test, and which version of H323 and your computer configuration please, thanks a million TC -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Scott Stingel Sent: Saturday, July 31, 2004 2:16 PM To: [EMAIL PROTECTED] Subject: RE: [Asterisk-Users] Asterisk scalability?

RE: [Asterisk-Users] Asterisk scalability?
Hi Tommy- I should have been clearer in the descriptions of my testing. I was testing only the PSTN load handling of asterisk using various models of Digium Quad PRI cards (400, 405, 410, etc). My testing did not add the CPU load which would be presented by the H.323, SIP, etc. So, you're right, one would expect lower results (ie: the ability to handle fewer lines) once those protocols were factored in. I am surprised that you're only able to get a single T1's worth however - that seems low given what others have claimed from time to time on here. Apologies for not being clear Scott Scott M.

Re: [Asterisk-Users] Asterisk scalability?
I don't know how relevant this info is to * doing iax-sip, but on the ser lists they posted these results for mediaproxy (written in python) and rtpproxy (written in C): In our tests, on a 1GHz Athlon CPU running linux 2.4.26 we got the following results: mediaproxy reaches 95% CPU load at around 60 simultaneous calls mediaproxy gets to 100% CPU load at 80-90 calls rtpproxy reaches 95% CPU load at 120 calls rtpproxy gets to 100% CPU load at about 150 calls I suspect 2.6 might be able to do a bit better, but doing iax-rtp on the media streams will take a bit more cpu than just proxying the rtp -JimC -- James H.
