OpenSER vs SER Performance Test

We often hear the question "Which is better OpenSER or SIP Express Router?". Well, now we know because we have completed a thorough and carefully controlled benchmark test of both SIP proxies. For an overview of our test, please see my blog from April 18th (OpenSER Performance Test). The complete test plan and results will be posted on www.transnexus.com soon.

The comparison results for 200 calls per second are:
.............................................CPU .........................Call
.........................................Utilization.............. Completion
OpenSER V1.1 .....................92.9% ......................97.17%
OpenSER V1.2 ....................83.3% .....................100.00%
SER 2.0 ..............................83.1% .....................100.00%

The comparison results for 220 calls per second are:
.............................................CPU .........................Call
........................................Utilization ...............Completion
OpenSER V1.1 .......................NA ...........................NA
OpenSER V1.2 ...................90.5% ......................99.79%
SER 2.0 .............................90.7% ......................93.43%

Conclusions:
- OpenSER V1.2 is significantly better than OpenSER V1.1 in terms of performance, call completion and post dial delay.

- OpenSER V1.2 and SER 2.o are identical in performance, but OpenSER V1.2 performed more reliably as it approached the limit of CPU utilization.

when you talked about calls per second, do you mean by "active calls per second" or "call setups per second"?

This performance test measured Call Setups per second.
