TCP To TCP Performance Test

This test measures the TCP output performance for each subject.

Design

  1. Each subjects is configured to receive and send data over TCP.
  2. The TCP producer and consumer are separate instances to help ensure performance is not tainted.
  3. Each subject is started and ran for 60 seconds.
  4. Performance data is collected and persisted to S3 for analysis.

Results

$ bin/comare -t tcp_to_tcp_performance
