Description
Single Session Echo Scenario
- FEJ has one acceptor session configured on the server host.
- The client application has one initiator session configured on the client host.
The overall process is following:
- Client application connects to the FEJ instance and sends 200000 FIX 4.2 messages with a rate of 5000 messages per second.
- FEJ receives the messages and matches them to the same session using business layer logic.
- FEJ responds to the client application with the same message in the same session.
The response time measured by the client application is the difference between timestamps:
- t1 - timestamp is taken right before sending a message to the client session;
- t2 - timestamp is taken right after receiving the same message in the client back from FEJ.
The round-trip time formula is: RTT=t2-t1 and is measured in microseconds.
