[Freeswitch-users] Performance bottleneck

I’m trying to determine the FS resource bottleneck when operating under load
(in windows environment), but can’t get the FS to load for some unseen
FS environment (a weak PC on purpose):
CPU 2x Intel Pentium 4 3GHz
RAM 2x 512MB DDR II RAM
Chipset - Intel E7221 (Copper River) chipset ICH6R + FWH + BCM5721
LAN 1x Broadcom Giga LAN
Windows 2003 Server – Service pack 2
FS version 9235
Running Release build on highest priority
A different machine running sipP
Running rtp_echo load, 50 cps, limit of 1000 calls, 30sec call duration,
extension 9996 (echo test):
sipp -rtp_echo -r 50 -l 1000 -d 30000 -s 9996 -sf auc.xml -mp 25000 -i
192.168.1.1 -mi 192.168.1.1 192.168.1.2
Test ran for 9.5 hours
Total of 48828 calls - all successful
No timeouts, retransmissions or unexpected messages.
Peak was 1003 calls after 4563 seconds (actual 0.2 cps)
Total of 1448750 RTP packets
Average response time: 11min 21 seconds
CPU usage 8% ~ 21%. Average 11%.
Started with 26,000KB RAM, 27,660KB VM, 25 threads
Peak at 136,000KB RAM,,367,004KB VM, 1024 threads
Ended with 88,220KB RAM, 141,684KB VM, 24 threads
Disk usage wasn’t monitored.
My question is what is slowing the response time so much but keeps the CPU
Following Patrick Grondin’s post from 17-Jul-08, I intentionally didn’t
change the default dialplan as I’m trying to load up the CPU.
