Approach

Benchmarks were run against two different versions of FIX Antenna Java (2.24.2 and 2.19.4), and the results were compared in order to detect possible regressions.

Single Session Echo Scenario

• FIXAJ has one One acceptor session is configured on server hostthe FIX Antenna Java side.
• Client application has one One initiator session is configured on the client hostapplication side.

 The overall process is following:

1. Client The client application connects to the FIXAJ instance FIX Antenna Java and sends 200000 FIX 4.2 messages with at a rate of 5000 50000 messages per second.
2. FIXAJ FIX Antenna Java receives the messages and matches it to the same session using business layer logic.FIXAJ responds to the client application with the same message in via the same TCP/IP connection (the same session).
3. The client application collects the response time histogram.
4. The process is repeated 5 times for each FIX Antenna Java version.

The response time measured by the client application 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 FIX Antenna Java)

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

Results

The performance of the FIX Antenna Java 2.24.2 release is almost the same as the performance of the FIX Antenna Java 2.19.4 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.
