This is a benchmark generator that measures the message and byte transfer rate between Erlang and Java nodes. It uses Erlang Distributed Protocol on the wire and Jinterface package for creating Java node which knows Erlang port mapper (EPMD), data types and its distributed protocol.
- In order to run this benchmark you need to have Erlang, Java and Gnu Make installed in your machine.
- Clone this repo into you machine
- Replace {message_count} and {message_size} with your benchmakr parameters and
- Execute
make MC={message_count} MS={message_size}command in its root
My machine info:
- OS: Debian 8
- RAM: 8 GB
- CPU: i5-4570 @ 3.20GHz
- Erlang: R17
- Java: 1.7
The result:
$ make MC=1000000 MS=1000
==> compiling java code
==> compiling erlang node
==> running java node
==> running erlang node
==> java node startd
==> erlang node started
==> Report:
====> Remote Node: java_node@localhost
====> Remote Process: java_process
====> Msg count: 1000000
====> Msg size (each): 1000 byte
====> Msg size (total): 1.0e3 mbyte
====> Msg rate: 47344.58654185623 msg/sec
====> Transfer rate: 47.34458654185623 mbyte/sec
====> Total time: 21.121739 sec
==> End- Messages are sent synchronously on one thread on each side
- Java Node acknowledges each Erlang Node message
- The acknowledgement message is same as the message itself
