server dual zeon 2.0ghz 4 gig ram
dual-port intel gig card teamed

Network switch 3com superstack 3 10/100 24 port layer 3

computer is

Amd 64 3200+ 2.0 GHZ
1.25 gigs of ram
32 bit os installed

windows 7 build 7600
NIC Reatek RTL8169/8110 gig GBE

average copy speed traverling 12 feet of cable and 1 switch is 7-12mbs

12mb/s is almost the maximum for 100mbit network.

You could hardly do any better.

1 byte is 8 bits.

100 megabit /8 = 12.5 megabyte

Nothing.

Read my post.

PS. upgrade to gigabit lan will get you 50 to 70mb/s, but you'll need gigabit cards and gigabit switch.

Isn't convention

100MB=100 megabyte

100Mb=100 megabit?

From 3 different networking sites The term "bps" specifies network bandwidth in bits per second. The term "Bps" specifies network bandwidth in bytes per second.

Net speeds are always mentioned in bits.

Regular card is 100 megabit = 12.5 megabytes.
Gigabit cards is 1000 megabit = 125 megabytes.

All theoretical of course, because you'll never reach those speeds.
In that light 12mb/s average is a wonderful score.

If net speeds are in bits why is he only getting 7-12 megabit from 100megabit switch?

average copy speed traverling 12 feet of cable and 1 switch is 7-12mbs

Isn't there another thread here where Realtek NICs are causing problems? They seem to be zeroing in on a driver problem...
