I have a Dell Optiplex 745 SFF<http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf> (Core 2 Duo) with an Intel PRO/1000 MT Dual Port Server Adapter<http://www.intel.com/products/server/adapters/pro1000mt-dualport/pro1000mt-dualport-overview.htm>
I am running 2.0-BETA4 (i386) built on Wed Oct 20 20:31:52 EDT 2010 I have the onboard Broadcom NIC disabled in the BIOS. I cannot achieve 100 mbps FD speeds. I can download at 100 mbps without any upload, and I can upload at 100 mbps without any download. But when I attempt to do both at the same time, my upload goes to 40 mbps while my download is at 100 mbps. I have tried this network card in another machine (HP Core 2 Quad) and it works perfectly under the same test conditions. I have the same problem with the 1.2.3 release of pfSense as well. I have tried enabling/disabling pooling and hardware offloading, but it does not fix my throughput issues. Any ideas?
