Ramesh Chaurasiya wrote: Hi, Whenever I try to receive traffic at more than 500 Mbps, many packets are being dropped as shown in ifconfig. There are many overruns and errors in Rx packets details of ifconfig. I am using Intel PRO 1000 Gigabit NIC, linux 2.4.20-8smp and dual processsor Xeon Machine with a 32bit/33 MHz PCI bus. What does this error means. Am I dropping packets at NIC/driver/kernel buffers/application socket? What new hardware should I use to overcome this. I am using latest e1000 drivers compiled with NAPI support. Please help me out. Thanks, Ramesh. Get a 64-bit PCI-X bus, and set the RxDescriptors and TxDescriptors in the e1000 driver to 4096. With that, I can get about 999Mbps rx + tx on two ports. Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com |
