Approach

Benchmarks were run against two different versions of FIX Antenna C++ (2.31.0 and 2.30.0), and the results were compared in order to detect possible regressions.

The following builds were tested:

• FIX Antenna C++ 2.30.0_580
• FIX Antenna C++ 6.31.0_595

Hardware

FIX Antenna Machine

• Intel(R) Xeon(R) CPU E5-2687 v3 @ 3.10GHz (2 CPU Hyper-Trading Enabled, 20 Cores)
• RAM 128 GB, 2133 MHz
• NIC Solarflare Communications SFC9120 (Firmware-version: 4.2.2.1003 rx1 tx1)
• Linux (CentOS 7.0.1406 kernel 3.10.0-123.el7.x86_64)
• SolarFlare driver version: 4.1.0.6734a

Client Machine

• Intel(R) Xeon(R) CPU E5-2687 v3 @ 3.10GHz (2 CPU Hyper-Trading Enabled, 20 Cores)

Benchmarks

Single Session Echo Scenario

• FIX Antenna has one One initiator session is configured on the server hostFIX Antenna C++ side.
• The client application has one One acceptor session is configured on the client hostapplication side.

 The overall process is following:

1. The initiator (FIX Antenna C++ connects to the client application ) sends 5000000 messages with an approximately constant rate (50000 msg/sec).The acceptor sends every incoming message back to the senderand sends 1000000 FIX 4.2 messages at a rate of 50000 messages per second.
2. The client application receives the messages and responds to FIX Antenna C++ with the same message via the same TCP/IP connection (the same session).
3. FIX Antenna C++ collects the response time histogram.
4. The process is repeated 3 times for each FIX Antenna C++ release version.

The response time measured by the client application FIX Antenna is the difference between timestamps:

• t1 - timestamp is taken right before sending a message to the

...

• socket
• t2 - timestamp is taken right after receiving the same message

...

• from the socket (from the client application)

...

So the round-trip time formula is: RTT = t2 - t1 and the measurement unit is measured in microseconds.

Results

The performance of the FIX Antenna C++ 2.31.0 release is almost the same as the performance of the FIX Antenna C++ 2.30.0 release. There is no performance degradation or improvement.

Performance value slightly differs from run to run due to the nature of the system used to measure the performance.
