Hi, I have an E3000 running Shibby 1.28.0000 MIPSR2-106 K26 USB Big-VPN. Using iperf on a pair of machines connected directly to it, I get around 110MBytes/sec using TCP. However, using multicast I only get about 22MBytes/sec. I have enabled "efficient multicast" and CTF. (Before I enabled them, I was getting around 11MBytes/sec). Is this expected? Is there anything else I can do to improve multicast throughput? Thanks.
