Hello. I have the opportunity to use an even more powerful server. I have just installed CentOS 5.5 64 bit, and compile freeswitch with 64 bits. This is the output with 100 simm calls using transcoding from G711 to G729 top - 16:57:56 up 6:04, 2 users, load average: 11.60, 12.49, 12.58 Tasks: 168 total, 1 running, 167 sleeping, 0 stopped, 0 zombie Cpu0 : 35.4%us, 0.6%sy, 0.0%ni, 63.6%id, 0.3%wa, 0.0%hi, 0.1%si, 0.0%st Cpu1 : 34.9%us, 0.6%sy, 0.0%ni, 58.8%id, 4.9%wa, 0.1%hi, 0.7%si, 0.0%st Cpu2 : 34.9%us, 0.6%sy, 0.0%ni, 59.6%id, 4.1%wa, 0.1%hi, 0.7%si, 0.0%st Cpu3 : 35.0%us, 0.7%sy, 0.0%ni, 62.0%id, 1.8%wa, 0.2%hi, 0.3%si, 0.0%st Cpu4 : 35.8%us, 1.3%sy, 0.0%ni, 62.5%id, 0.2%wa, 0.0%hi, 0.1%si, 0.0%st Cpu5 : 35.6%us, 1.6%sy, 0.0%ni, 60.1%id, 1.8%wa, 0.1%hi, 0.8%si, 0.0%st Cpu6 : 35.8%us, 1.9%sy, 0.0%ni, 59.9%id, 1.5%wa, 0.1%hi, 0.8%si, 0.0%st Cpu7 : 36.5%us, 2.0%sy, 0.0%ni, 60.6%id, 0.7%wa, 0.0%hi, 0.2%si, 0.0%st Mem: 8165808k total, 1208292k used, 6957516k free, 150228k buffers Swap: 10223608k total, 0k used, 10223608k free, 772980k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5265 root 18 0 541m 79m 5796 S 469.5 1.0 1077:32 freeswitch 1 root 15 0 10348 684 572 S 0.0 0.0 0:01.24 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00 Is normal the load average?
