> Performance in terms of what? -sc Quite honesty, any sort of positive result. I'm basically just trying to get a handle on what type of real-life situations these settings are intended to benefit. Does semi-polling mode result in less CPU being occupied by "interrupt" state at high bandwidth levels when many IPF rules are being used, for example? Do either of these settings result in lower latency or higher throughput at high bandwidth levels? I don't have a firm handle on what specific real-life issues these two new features were intended to address so I'm not 100% sure how to phrase my question. Russell Brunelle
