I have a boat load of cat5e patch cords coming to see if my bottleneck can be relieved. I also need to order a few PCIE slot NIC cards. Egads! It's only money I suppose. Silly me, I'm retired so it shouldn't matter what speeds I get but I paid for gigabit equipment so I want the speeds to go with it.
