Quite possible that either 1 or both of his nics are just crap..
He could spend a few bucks and get some decent nics, but he has that trip to save for
So for example, I have this popcorn A 110 little media box.. The thing rocks, plays whatever you throw at it -- love the thing.. When I first got it I had put a disk inside of it and stored files on it, it had some apps you could run on it if you had a disk inside, etc. You could telnet to it, etc..
Well it has a supposed 100mbit nic.. Thing is it could/can barely push 65mbit.. Just balls to the wall nothing but just simple iperf test and it can not even push 80 mbps. Is it the nic, is just the device itself designed more for playing video than pushing packets?
Well if all its doing is playing video, it really doesn't need 90+ mbit out of a 100 like every other 100mbit card out there.. You can watch 1080p over the wire with 65mbit just fine.. So as a media player its great, but putting a disk in it and using it as a nas.. not so much
So pulled the disk and just use it as a media player and its slow speed never becomes and issue.
Now if he wants to move files between his machines faster than paint dries then he will have to do something.. But if he is just surfing the net, watching movies off the other machine, etc.. 30MBps is quite fast..
My nephew was over the other day, had his laptop -- he wanted some video files of tv shows and movies he had not seen.. Most of moved 60 some GB to his laptop.. Well sure and the hell was not going to move that amount of stuff via wireless, plugged him in and was getting 80MBps plus while starting the copies down to 60MBps seemed to be about lowest it went never the very end of a folder -- I know 1 folder was 17GB.. only took a couple of minutes..
Now does it really matter if it takes 2 minutes or 10 minutes to copy something.. Its up to him..
