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:

1. Client application connects to the FEJ instance and sends 200000 FIX 4.2 messages with a rate of 5000 messages per second.
2. FEJ receives the messages and matches them to the same session using business layer logic.
3. 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.
