The original test was done on git master at the date mentioned. The sqlite core.db file was on /run/shm which is a tmpfs on unbuntu 12.04. I will be recompiling from git master and test running with -nosql. Testing my existing setup with -nosql seems more stable now running at 210CPS for some time (500k calls already passed) with ~35% idle cpu. But the free mem is slowly going down. I will let it run untill the kernel will kill it to see how many calls it can handle. During my tests i did not run FS with RT priority but according to htop some of the threads are scheduled as RT. My setup is doing bypass-media , thus FS handling only call establishment and teardown on both legs. cat /proc/<FS pid>/status Name: freeswitch State: S (sleeping) Tgid: 15995 Pid: 15995 PPid: 1 TracerPid: 0 Uid: 999 999 999 999 Gid: 999 999 999 999 FDSize: 64 Groups: VmPeak: 5002808 kB VmSize: 5002088 kB VmLck: 0 kB VmPin: 0 kB VmHWM: 625900 kB VmRSS: 624156 kB <-- this is going up VmData: 4855788 kB VmStk: 136 kB VmExe: 20 kB VmLib: 18288 kB VmPTE: 2352 kB VmSwap: 0 kB Threads: 1866 SigQ: 0/18446744073709551615 SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000000000 SigIgn: 0000000010003006 SigCgt: 0000000180014209 CapInh: 0000000000000000 CapPrm: 0000000000000000 CapEff: 0000000000000000 CapBnd: ffffffffffffffff Cpus_allowed: ffffff Cpus_allowed_list: 0-23 Mems_allowed: 00000000,00000003 Mems_allowed_list: 0-1 voluntary_ctxt_switches: 1803 nonvoluntary_ctxt_switches: 23 output of 'top -H' at 180CPS top - 15:27:00 up 2 days, 5:32, 5 users, load average: 8.19, 91.07, 65.03 Tasks: 2066 total, 3 running, 2063 sleeping, 0 stopped, 0 zombie Cpu(s): 50.1%us, 3.9%sy, 0.0%ni, 45.9%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st Mem: 4038512k total, 2282260k used, 1756252k free, 114112k buffers Swap: 0k total, 0k used, 0k free, 1165868k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 16000 freeswit RT -10 4885m 594m 4964 R 69 15.1 3:10.26 freeswitch 16009 freeswit RT -10 4885m 594m 4964 S 33 15.1 1:26.20 freeswitch 16008 freeswit RT -10 4885m 594m 4964 S 28 15.1 1:17.30 freeswitch 16007 freeswit RT -10 4885m 594m 4964 S 4 15.1 0:10.80 freeswitch 16004 freeswit RT -10 4885m 594m 4964 S 2 15.1 0:06.63 freeswitch 19171 root 20 0 18988 2948 944 R 2 0.1 0:00.64 top 18735 freeswit -2 -10 4885m 594m 4964 S 1 15.1 0:00.29 freeswitch 16003 freeswit -2 -10 4885m 594m 4964 S 1 15.1 0:01.61 freeswitch 16690 freeswit -2 -10 4885m 594m 4964 S 1 15.1 0:00.42 freeswitch 16730 freeswit -2 -10 4885m 594m 4964 S 1 15.1 0:00.42 freeswitch 16750 freeswit -2 -10 4885m 594m 4964 S 1 15.1 0:00.45 freeswitch 16764 freeswit -2 -10 4885m 594m 4964 S 1 15.1 0:00.44 freeswitch <more of the above> .... ....

I can't reproduce such cps load on my ARMv5TE system. ) bratner, please give us 'top -H'. I guess freeswitch running at realtime priority.

Sqlite is probably getting hammered... Trust me... Mount the fs db dir as tmpfs or use the –nosql flag when starting freeswitch
I routinely run dialer traffic at much higher CPS then that

bi, bo and wa field is low, so it seems that is not disk subsystem.

You are probably hammering the disk subsystem... Keep in mind that FS uses multiple sqlite databases by default... Mount the fs db dir as tmpfs and try again

Hm... But what about huge interrupt and context switching number?
