This comes out to about 12 to 16 megabit/seond. I've read in forums that people are getting much higher speeds (ie: "40-60 Mb/s" http://forums.cnet.com/5208-7589_102-0.html?threadID=265967). I'm getting my benchmark by having a unmanged 5 port switch connected to a WRT54GS router connect. I'm sending a file from a computer connect to the WRT54GS to another computer that's connect to the unmanaged 5 port switch. Is the linkage of the switch causing this massive overhead? i doubt it. What could explain the slow down? electrical interference?
At a full 100Mbit/sec link the max would be roughly 12Mbytes per second. Since you're getting less than that by a factor of 8 I would suggest there is a problem somewhere.
Right now you say your source computer is connected to the router and your target is connected to the switch. I suggest you connect them both to the switch and try it again to eliminate the connection from the switch to the router as a possible problem.
A little bit slow for windows file transfer.
I'd expect 3.3 megabytes per second and you're getting half that.
100/10 ~= 10 Megabytes per second raw ethernet at roughly 8 bits per byte plus overheads.
then windows tops out at about 30% of any given network. consider it MS tax.
so 30% of 10 is 3.3 megabytes per second.
So yes, below normal, but not markedly.
cableas are okay and both computers have clean 100meg connections ?
If you're getting link errors that will slow things down.
Check both pc's using the manufacturers diagnostics for the cards in question. (for most vendors it installs by default from their driver disks.)
