I've got a file server with 2 NICs at home. One NIC is 10/100 and plugged into a hub so it's accessible from all computers on the network. The other NIC is 1Gbit and is plugged directly into my main PC with a CAT6 crossover cable. This is so I can transfer large files at higher speeds between the two computers.
However when testing speeds with a large file last night, both NICs seemed to transfer at the same speed (30-40Mb/s). I checked the connection, Windows reports the gigabit connection is running at that speed and the LEDs on the NIC indicate that it is running at full speed.
I'm wondering if it's the hardware on the file server. It's only a Celeron 400Mhz, 192Mb, IDE HDD running FreeNAS embedded.
Anyone have a suggestion as to why this isn't working as expected?
