Bandwidth is not a problem, we can get 10mbps without a hitch. But we would like to know the scalability on the CPU vs the number of clients. So far, for both kernels, we're getting 50% CPU utilization using 500 clients and 384 burst kbps each. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
