Softswitch performance

Single server performance

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

• MOR - 500 concurrent calls*
• M2 - 1000 concurrent calls*

'* We cannot guarantee such amount of concurrent calls as many factors influence it:

• Hardware specifications (CPU, RAM, HDD type - 5400/7200 rpm, SSD, SAS, Raid, etc.)
• Network (routers/switches)
• Providers (connectivity, quality, PDD)
• CPS (if you accept a lot of short calls at the same time (so called dialer or call center traffic), softswitch performance decreases)
• Structure of call (signalling only or signalling with media)
• 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)
• Codec and protocol used
• Protocol and codec conversion (in case of 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)
• DB and GUI on same server or on the separate (if you separate DB and GUI, you can increase performance)
• SIP balancer present or not (if you use SIP balancer in front of the servers, you can increase performance)
• Business model (Calling Card, Callback and Call Center calls decreases softswitch performance)
• etc

Multi-server performance

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