This is a laptop (Dell Precision M6500) talking to the on-board NIC on a consumer-grade motherboard. According to ifconfig, it's using an MTU of 1500 bytes. This is not using MythTV; it's simply using scp or rsync to copy files around. Obviously I'm not doing that continuously, but when I'm moving a lot of data (20-30 GB isn't uncommon), I want it to be fast. WiFi is simply not efficient for that. > If you were doing video editing then that would be a different story. > This is large(ish) scale bulk data transfers where high sustained > throughput is necessary.
