benchmark-socket

A benchmark application comparing performance aspects of various transport approaches:

• Socket
• Rsocket
• ZMQ

Execution

Project consists of 2 separate applications. They are configured to be automatically compatible for each transport.

• Pitcher: Responsible for throwing the messages using the specified transport
• Catcher: Responsible for receiving using the specified transport

Running a benchmark is a matter of running a Pitcher and Catcher pair specifying the correct main class as well as a transport type.

# For Pitcher
java -jar benchmark-socket.jar dev.tomek.benchmarksocket.pitcher.Pitcher --transport=<transport-name>

# For Catcher
java -jar benchmark-socket.jar dev.tomek.benchmarksocket.catcher.Catcher --transport=<transport-name>

Possible transports:

socketPlain
socketRefined
rsocket
zmq
