Performance Bottlenecks

  1. Need to identify performance bottlenecks. Looks like TAO has slowed down a bit over the past two betas. Need to identify the bottlenecks before improving the performance.
  2. Its a known fact that thread-per-connection is faster than the reactive model, even for single threaded cases. Need to identify portions of the reactor that slows down things and fix them or create a fast path in the ORB just using plain vanilla select for the server.
  3. In the output data path, the CDR creates the message block and all other associted things on TSS. If we could change the CDR to first create them on the stack and then move the data to TSS we could achieve better performance for small messages.

Features

  1. Implement DP-CORBA specification
  2. Implement TII specification.
