The last time I measured it, Linux blows MacOSX out of the water for UDP latency, which is what really matters for HFT (like by a factor of 2 or more). There are several vendors (including my company) that sell UDP offload solutions, which gets the UDP latency down even further (like in 3us range, wire to app). However, these solutions are generally linux or Windows focused (Myricom DBL, Solarflare, etc). This email sent to site_archiver@lists.apple.com
