You go tend to your knitting. I have a family of four, plus occasional guests. If I had every device that could be connected to ethernet connected to wifi, I would spend all my time debugging wifi problems. On a Saturday afternoon, it is not unusual to see: - one person watching NetFlix. - one person watching MythTV. - one person playing a video game while listening to music from YouTube. - one person trying to get work done - a bunch of wifi devices chirping away at the internet, and - a couple of backups in progress. and as for jumbo packets: $ netperf -H splat -p 20000 -l 30 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to splat () port 0 AF_INET : demo Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 30.01 940.42 $ ip l 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 So, no, you don't need jumbo packets to get 900+Mb/s out of your 1000Mb/s ethernet connection. That's through a very boring Netgear $50 switch. -dsr-
