We ran a benchmark test of OpenSER and RTPproxy to understand the relation
between CPU capacity and the number of simultaneous calls that could be
managed with acceptable call quality.
OpenSER V1.3 and RTPproxy V1.0 were hosted on a Dell Precision 490 server
with two Intel Xeon 5140 dual core, 2.33 GHz CPUs and 4 GB of RAM. Three
CPU cores were disabled for the test. The test was run using just a single
CPU core. Multiple SIPp clients directed traffic to OpenSER which queried
an OSP server for call routing instructions. The test was designed for each
call to require an average of two retries before the call was completed to a
SIPp server on the third try. The two-way RTP stream for each call flowed
through the RTPproxy. Call Detail Records for each call attempt were sent
from OpenSER to the OSP server.
OpenSER and RTPproxy, using a single core of the 2.33 GHz CPU, can manage up
to 750 simultaneous calls.
