Hi all
i am going on with some performance tests on a 10gbe network card with FreeBSD.
I am doing this test: I send UDP traffic to be forwarded to the other port of
the card on both the card ports.
Using 1492-long packets i am uppering the number of packets per second i sent
In order to see wi
question, you can't use LRO in that case of course.

Your nmbclusters is very low, you list it twice so I'm assuming the second
value is
what it ends up being, 32K :(
I would set
ing going wrong with interrupt coalescing,
but I can't find out what.
Any idea?

Ray,

This is my loader.conf
kern.ipc.nmbclusters=65635
kern.hz=1000

Hi all
I am doing some tests on a BSD system with a 10gbe Intel based network card and
I have some doubts about the configuration since the performance I am
experiencing looks (very) poor.
This is the system I am doing test on:
- HP 380 G5 (XEON X5420, CPU speed: 2.50GHz, BUS speed: 1333 MHz
13 matches
