I need some help from you. I am using 2 xeon(2
GHz) machines each with two processors running linux
2.4.20-8smp kernel and having intel PRO/1000 gigabit
adapter NIC card(e1000 driver). I tried connecting
both of them using a gigabit switch. I am getting
gigabit speed only if I use my own TCP sockets sending
packets of size around 1400 bytes. If I send packets
of size around 500 bytes, I am getting maximum of only
500 Mbps. I noticed that NIC is receiving all the
packets but they are getting dropped in the kernel.
I tried changing the settings like
netdev_max_backlog to 30000 and rmem_max, wmem_max and
txqueuelen, but of no use. Can you please suggest some
changes that I need to make to achieve this speed.
(Like changing number of Rx interrupts, Tx interrupts
etc). Can you please suggest some other links where I
can get some useful information. Will linux router
project LRP help me to achieve it.
