Performance comparison of Thrift, Protocol Buffers, JSON, EJB, other?

Question

We\'re looking into transport/protocol solutions and were about to do various performance tests, so I thought I\'d check with the community if they\'ve already done this:

Answer 1

I have done a study for spring-boot, mappers (manual, Dozer and MapStruct), Thrift, REST, SOAP and Protocol Buffers integration for my job.

The server side: https://github.com/vlachenal/webservices-bench

The client side: https://github.com/vlachenal/webservices-bench-client

It is not finished and has been run on my personal computers (I have to ask for servers to complete the tests) ... but results can be consulted on:

• Laptop: https://github.com/vlachenal/webservices-bench/blob/master/results.md
• Desktop: https://github.com/vlachenal/webservices-bench/blob/master/results-desktop.md

As conclusion :

• Thrift offers the best performance and is easy to use
• RESTful webservice with JSON content type is pretty close to Thrift performance, is "browser ready to use" and is quite elegant (from my point of view)
• SOAP has very poor performance but offers the best data control
• Protocol Buffers has good performance ... until 3 simultaneous calls ... and I don't know why. It is very difficult to use: I give up (for now) to make for it work with MapStruct and I don't try with Dozer.

Projects can be completed through pull requests (either for fixes or other results).
