I'm doing some experiments with high frame rates, using a PRO/1000 MT Server Adapter and a hand-made driver for linux 2.6.4. The card is plugged in a 2.4 GHz dual-Xeon through a 100 MHz PCI-X interface, and it's receiving a lot of small (60 + FCS) frames. My problem is that the card seems to have a limit at approximately 1.08 Mpps: I'm not able to transfer more than that amount of packets to the RAM, also if the CPU is almost idle. Is anybody able to tell me if the bottleneck is the chipset or the PCI-X bus? Is it better to try a motherboard with 133 MHz PCI support or to buy a card with a better chipset (e.g. 82546 or 82547)? Is the 82545 supposed to support a network fully loaded with 60 bytes packets? Thanks, Loris |
