We have conducted extensive performance tests for Ice, and compared the results against TAO, a popular high-performance CORBA implementation.

You can view our results here:

We have tried to perform the tests as carefully and fair as possible, and have provided all information that is required to independently reproduce our results. Should there be anything unclear about how we conducted the performance tests, please feel free to use our forums to post your questions:
