title: Performance comparison of Thrift, Protocol Buffers, JSON, EJB, other?
body: <p>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:</p>
  <p>Has anyone done server performance tests for simple echo services as well as serialization/deserialization for various messages sizes comparing EJB3, Thrift, and Protocol Buffers on Linux?</p>
  <p>Primarily languages will be Java, C/C++, Python, and PHP.</p>
  <p>Update: I'm still very interested in this, if anyone has done any further benchmarks please let me know. Also, very interesting benchmark showing compressed JSON performing similar / better than Thrift / Protocol Buffers, so I'm throwing JSON into this question as well.</p>
