Re: [SR-Users] Seeing Large Waits

Hi Mack, What sort of end-to-end delays are you seeing, from receipt of request until immediately before t_relay()? You can profile this with the benchmark module: https://kamailio.org/docs/modules/5.1.x/modules/benchmark.html Or my preferred method, the hard way: # At the practical start of request processing. $avp(proc_start) = $TV(Sn); # At the end, right before calling t_relay() or forward(). $var(cur_time) = $TV(Sn); $var(proc_diff) = ( ((( $(var(cur_time){s.select,0,.}{s.int}) - $(avp(proc_start){s.select,0,.}{s.int}) ) * 1000000) + ( $(var(cur_time){s.select,1,.}{s.int}) - $(avp(proc_start){s.select,1,.}{s.int}) ) / 1000) mod 1000 ); xlog("L_INFO", "[R-MAIN:$ci] -> Request processing delay: $var(proc_diff) ms\n");); Also, for general background on this topic, you might consider my article on the subject of Kamailio performance characteristics: http://blog.csrpswitch.com/tuning-kamailio-for-high-throughput-and-performa… If I had to guess, shooting from the hip, you've got some really slow database queries somewhere. -- Alex On Wed, May 02, 2018 at 06:19:00PM -0400, Mack Hendricks wrote: -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/
