No, but I can show you a series of slides with performance compared to
Mellanox, and a histogram of the actual message sizes and rates of the
programs. In the case where the messages are short and frequent, we
end up with a large performance advantage. So if that's what your app
does when it scales, you can draw your own conclusion.
