Here are device’s characteristics
An over-clocked Raspberry PI 3 running Raspbian Stretch with a U3 MicroSD card. pi@raspberrypi:~ $ cat /etc/issue Raspbian GNU/Linux 9 \n \l pi@raspberrypi:~ $ uname -a Linux raspberrypi 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l GNU/Linux pi@raspberrypi:~ $ cat /boot/config.txt ... total_mem=1024 arm_freq=1300 core_freq=500 sdram_freq=500 sdram_schmoo=0x02000020 over_voltage=2 sdram_over_voltage=2
His remarks on Kamailio’s sr-users mailing list:
The tests ran for 60 seconds, repeated a couple of times, and they were done in a LAN, using PI’s ethernet interface, running Kamailio 5.1.1.
- REGISTER/200, __with db_text__
– at 900 cps test did finish: all UAC registered; pi htop threads were ~15-20%
– at 950 cps test did NOT finish: got “Overload warning” on my UAC/UAS SIPp testing machine
- INVITE/180/200/PAUSE(3sec)/BYE/200, __with no media__
– at 370 cps test did finish: all UAC->UAS calls completed; ~150 “180 Trying” Unexpected-Msg on UAC side; pi htop threads were ~50%
– at 380 cps test did NOT finish: few(~5) UAC->UAS calls not completed; pi htop threads were ~50%
The results are really impressive (even if the used testing configs were really basic ones)!!!
Moreover, I think that I’ve reached the limit of my current SIPp testing machine, but not of PI’s.
