Performance tests



Goal - to run at least 700 calls on this server.

Hardware

  • Local LAN with 100mb cheap DLink switch
  • Laptop to initiate calls over sipp
  • Tested server:
HP Proliant DL160 G5 E5405
1 x Quad Core Xeon 2Ghz
2 Gb RAM
Asterisk 1.4.18.1
Centos 5.2


Asterisk configuration

For test standard /var/lib/asterisk/sounds/tt-monkeys.gsm from HDD (not from RAM) was used.

sip.conf

[general]
context=playback_test
;rtptimeout=60  
;rtpholdtimeout=300
[1000]
type = friend
host = dynamic
username = 1000
secret = 1000
nat = no
context = playback_test
disallow = all
allow = alaw


extensions.conf

[playback_test]
exten => _X.,1,Answer
exten => _X.,2,Background(tt-monkeys)
exten => _X.,3,Goto(2)


sipp

./sipp -inf users.csv -sf uac_gsm.xml -i 192.168.0.130 -s 123 192.168.0.191
File:Uac gsm.xml <-- uac_gsm.xml file


Testing

Starting from 500 calls, we increased calls at a rate of 20 calls per second (cps).

Stats can be seen on following screenshots. Accumulated stats are at the end.

At each step we dialed additionally with X-Pro to test how it sounds.

  • Sipp background 504 calls.png 504 calls
  • Sipp background 605 calls.png 605 calls
  • Sipp background 703 calls.png 703 calls
  • Sipp background 806 calls.png 806 calls
  • Sipp background 909 calls.png 909 calls
  • Sipp background 1002 calls.png 1002 calls
  • Sipp background 1143 calls.png 1143 calls

Results

Sipp background stats.png


At 1143 calls, the network limit was reached and calls started to drop.

We were able to reach our goal - that is, 700 sim. calls on this server.

Future

In future I see no problem in reaching 2000 calls. Changes that should be made:

  • A smaller codec should be used, e.g. GSM
  • 1 Gbit network instead of the 100 Mbit we used
  • More RAM, a second CPU, sound files stored into RAM instead of HDD
