Conclusions
- RAM is not important sending calls. Maximum usage 2.5 Gb was reached but mainly due to GUI usage (Active Calls and some stats pages)
- CPU is very important - the faster, the better
- SSD disc RAID1 really helped a lot in high CPS sessions
- MySQL service took < 10% at peak times and is not important
- Asterisk service takes major CPU power and is main bottleneck in the long run
- Voice quality degrades at the time of high CPS (high HDD usage)
- 20 CPS reached without problems, if more - Asterisk chokes
Used hardware
3 equal servers:
| CPU: | Intel Core i5-2400 (4 Cores) |
| HDD: | 2x 120 GB SSD (RAID1) |
| RAM: | 16 GB DDR3 |
| LAN: | 100 Mbps |
Setup
Origination server -> Measured Server -> Termination server
One call was always life for testers to hear audio (MOH), to notice when quality degrades.
Calls were originated using script which generates call files in batches (5-10-20-50-100).
Destination was random in a format XXXXXXXXXX, where X in [0..9]
