OpenSIPS tests for performance degradation

We have performed some tests using OpenSIPS 1.6.4 to simulate some real life scenarios, to get an idea on the load that can be handled by OpenSIPS and to see what is the performance penalty you get when using some OpenSIPS features like dialog support, DB authentication, DB accounting, memory caching, etc.

A total of 11 tests were performed, using 11 different scenarios. The goal was to achieve the highest possible CPS in the given scenario, store load samples from the OpenSIPS proxy and then analyze the results. The base test used was that of a simple stateful SIP proxy. Than we kept adding features on top of this very basic configuration, features like loose routing, dialog support, authentication and accounting.... read more

Load monitoring and troubleshooting

OpenSIPS trunk was enhanced with some new functionality for load

As part of the effort of making OpenSIPS project as open and as interactive (to the users) as possible, we plan to start a program of public online meetings with the community - the basic idea is to try to involve as much people as possible in the process of running and guiding the OpenSIPS project -via a open and public discussion :)

Identify issues that needs to be addressed - issues may be technical (like tech work, features, improvements, contributions, etc) or management (lists, SVN/GIT, etc). NOTE: the meetings will identify the issues, we DO NOT plan to resolve the issues during these meetings (who, how and when to solve will be decided in the meeting)... read more
