Description

Single Session Echo Scenario

  • FEJ has one acceptor session configured on server host.
  • Client application has one initiator session configured on 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 it 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 client application is the difference between timestamps:

  • t1 - timestamp taken right before sending message to client session;
  • t2 - timestamp taken right after received the same message in client back from FEJ.

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