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.
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.
