I now have a 1.8ghz CoreDuo MacMini and 2.0ghz MacBook and both have gigabit Ethernet cards in them, based on the Marvell Yukon chipset i believe. I was wondering upto what speeds people have driven these ethernet cards? I'm doing some testing using iperf version 2.0.4 but I can't seem to get any more than around 30MB/sec out of the cards. Is this their limit? Have you managed to get better out of them? If so, how? Synology have just brought out a NAS box (DS209), that reads and writes at around 60MB/sec, but pretty pointless unless your ethernet card is upto the same speeds. Are there also performance bottlenecks on the newer Mini's too? Any help would be appreciated.
