hi, all
I am using debian linux( the kernel is linux-2.6.30 ) as the OS, and the
hardware is 5000P. The network card is *Eight Intel 82571EB. I use linux
default network divice driver£¨e1000?£©.*
**
*My product need high performance of network t*ransmitting rate. But the
test result is not good. The *t*ransmitting rate of 64bytes small packets
is only 30% of line speed.
How can I get higher performance of 64bytes small packets *network
t*ransmitting
rate? How can I improve the 64bytes small packets *network t*ransmitting
rate upto 90% - 100% of line speed? I know that somebody has maded it.
where is the performance bottleneck of linux os? Somebody says that it
is about the linux e1000 driver. what should I modify about the
e1000 driver? (NAPI? MMAP? sk_buffer? which one is the answer£¿) * *
**
Thank you very much!
