Softswitch performance

Single server performance

Performance results in the following conditions (recommended hardware is used, SIP protocol, no transcoding, CPS is low (<5), other processes than calls are not in use) are:

• MOR - 500 concurrent calls with media, 4000 concurrent calls (only signalling)
• M2 - 1000 concurrent calls with media, 8000 concurrent calls (only signalling)

Multi-server performance

If you need better performance than single server solution can offer, you should use multi-server implementations.

Factors which determine call performance

Call capacity vary depending on the following factors:

• Hardware specifications
• Structure of call (you will get 8 times better performance if you send just the signalling without media through the softswitch)
• Processes, running on the same time (if you generate invoices, statistics or run other processes, softswitch performance decreases)
• Additional functionality usage (if you record calls, use different IVR structures, softswitch performance decreases)
• Transcoding (if you do transcoding, performance decreases two times)
• Calls length (if you accept a lot of short calls at the same time (so called dialer or call center traffic), softswitch performance decreases)
