By the time you hit 20k-30k CPS, you start to run into <br>> hardware, scheduler and kernel-side limits that need tweaking.<br>> <br>> The actually-existing, real-world throughput of a Kamailio installation <br>> is limited by the fact that static configurations aren't very useful for <br>> all but the simplest implementations. Most nontrivial applications of <br>> Kamailio involve calling out to a database, API or something of that <br>> nature at least once during the call processing cycle. Waiting on a <br>> response from that source is a synchronous process, and thus blocks <br>> Kamailio's (architecturally) limited number of SIP receiver threads.<br>> <br>> But even with such limitations in mind, you should still be able to get <br>> 200 CPS easily in all but the most exceptionally poorly-designed <br>> implementation. 200 CPS isn't very much.<br>> <br>> -- Alex<br>> <br>> P.S. We specialise in getting thousands of CPS out of Kamailio while <br>> still doing _lots_ of SQL queries for routing.<br>> <br>> On 06/17/2015 11:17 AM, Jonathan Hunter wrote:<br>> <br>> > Hi Guys,<br>> ><br>> > Has anyone recently performed tests on kamailio 4.2 running up to 200 CPS?<br>> ><br>> > It would be great to know the hardware requirements for this setup.<br>> ><br>> > Thanks<br>> ><br>> > Jon<br>> ><br>> ><br>> > _______________________________________________<br>> > SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list<br>> > sr-users@lists.sip-router.org<br>> > http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users<br>> ><br>> <br>> <br>> -- <br>> Alex Balashov | Principal | Evariste Systems LLC<br>> 303 Perimeter Center North, Suite 300<br>> Atlanta, GA 30346<br>> United States<br>> <br>> Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct)<br>> Web: http://www.evaristesys.com/, http://www.csrpswitch.com/<br>> <br>> _______________________________________________<br>> SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list<br>> sr-users@lists.sip-router.org<br>> http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users<br></div></div> </div></body>
