We recently ran a performance test of Asterisk configured as a SIP Back to Back User Agent (B2BUA). The test platform hosting Asterisk was a $1000 Dell PowerEdge 840 with a Quad Core Xeon X3220, 2x4M cache, 2.40 GHz, 1066 MHz FSB and 4 GB RAM. Redhat V5 was the operating system. The test was [...]

OpenSER and RTPproxy Performance Test
September 20th, 2008 
Jim_Dalton We have published results from a performance test of OpenSER V1.3 and RTPproxy V1.0 running on the same host server. The purpose of the test was to understand the relationship between server CPU performance and the maximum number of simultaneous calls. The massive scalability of SIP signaling with OpenSER is well known. For this test [...]

Asterisk Performance Testing
September 18th, 2007 Jim_Dalton Over the last couple of months we have been stress testing Asterisk V1.4 to understand its performance. We started using V1.4.4 and advanced to V1.4.11 as new releases were made available. We have been stress testing Asterisk configured as a SIP Back to Back User Agent (B2BUA) installed on a server with two, dual core, [...]
OpenSER vs SER Performance Test
April 27th, 2007 Jim_Dalton 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 [...]

April 19th, 2007 Jim_Dalton This post is follow-up on my post yesterday about our performance testing of OpenSER V1.1, so please refer to that post for details on the test setup and test scenario. We have completed our performance testing of OpenSER V1.2. The comparison results are: V1.1 – 200 calls per second – 92.9% CPU Utilization – 97.17% [...]
OpenSER Performance Benchmark
April 18th, 2007 Jim_Dalton We continue to see a growing number of service providers using SIP Express Router (also known as SER) and OpenSER as infrastructure SIP proxies for their carrier operations. SER (www.iptel.org) and OpenSER (www.openser.org) are mature open source projects for a very stable, high performance SIP proxy. SER was the original project and OpenSER is fork [...]
