Machine [1] is an older Thinkpad T61 (running the Live system), Machine [2] the well-known "FreeBSD" machine from the previous benchmark. Both machines run FreeBSD 9.1-RC1 GENERIC. {Values in MBit/s} Configuration IPv6 IPv4 --------------------------------------- [1] -> [2] 450 600 [2] -> [1] 401 855 This confirms the FreeBSD IPv6 receive rate measured with Linux as sender (iperf client).
