Hello. I’m new at Freeswitch. I just installed the versión : FreeSWITCH version: 1.0.head (git-c64f475 2011-01-18 14-36-30 -0500). I also installed the codec g729 for transcoding from g711 to g729 (for testing purposes only). I have near 120 simmultaneous calls and I’m having this use of CPU. top - 15:14:29 up 21:49, 3 users, load average: 15.15, 15.66, 16.11 Tasks: 118 total, 2 running, 116 sleeping, 0 stopped, 0 zombie Cpu0 : 49.7%us, 1.7%sy, 0.0%ni, 48.1%id, 0.2%wa, 0.0%hi, 0.2%si, 0.0%st Cpu1 : 49.5%us, 1.7%sy, 0.0%ni, 48.3%id, 0.3%wa, 0.0%hi, 0.2%si, 0.0%st Cpu2 : 48.8%us, 1.8%sy, 0.0%ni, 48.3%id, 0.6%wa, 0.1%hi, 0.5%si, 0.0%st Cpu3 : 47.2%us, 2.2%sy, 0.0%ni, 47.4%id, 0.4%wa, 0.5%hi, 2.4%si, 0.0%st Mem: 2073316k total, 2024396k used, 48920k free, 159660k buffers Swap: 4192944k total, 72k used, 4192872k free, 1678300k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 21944 root 20 0 130m 70m 4784 S 385.5 3.5 420:08.69 freeswitch 1 root 20 0 2012 776 572 S 0.0 0.0 0:00.95 init 2 root 15 -5 0 0 0 S 0.0 0.0 0:00.00 kthreadd 3 root RT -5 0 0 0 S 0.0 0.0 0:00.09 migration/0 4 root 15 -5 0 0 0 S 0.0 0.0 0:02.70 ksoftirqd/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 6 root RT -5 0 0 0 S 0.0 0.0 0:00.09 migration/1 7 root 15 -5 0 0 0 S 0.0 0.0 0:02.66 ksoftirqd/1 8 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 9 root RT -5 0 0 0 S 0.0 0.0 0:00.04 migration/2 10 root 15 -5 0 0 0 S 0.0 0.0 0:02.25 ksoftirqd/2 11 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/2 I have a server with Intel(R) Xeon(R) CPU Quad Core @ 2.33GHz and 2 Gig of RAM. Is this use of CPU normal with this number of active calls?. Remember that I’m doing transcoding. I also made this setup : ulimit -c unlimited ulimit -d unlimited ulimit -f unlimited ulimit -i unlimited ulimit -n 999999 ulimit -q unlimited ulimit -u unlimited ulimit -v unlimited ulimit -x unlimited ulimit -s 240 ulimit -l unlimited Can someone help me here? Thanks Ricardo.-
