I did try it, same problem occured. It disappered when I disabled
hyperthreading in bios.
6.0- beta 5 and rc1 works fine with all features enabled.

I have a server with a Supermikro mainboard and two Xeon 3.0Ghz/2MB.
When running kernel with SMP support the network performance is very

performance is as espected and very good.
I have tried some different GB nics and the problems is static and
independent of modell/brand.
I have also disabled as much as hardware possible, no usb, sio and etc.
Typical indicator is also that the load on the box is skyrocketing
when it starts to serve nfs client, but the cpu load is very load.
Is there any way around this problem?
Is it possible for you to test using an i386 install rather than an
amd64 install, for reference? I use Xeon SMP test hardware in the
netperf cluster, and have no problem saturating multiple gigabit
ethernet links with either UP or SMP kernels. However, all the Xeons I
have access to are 32-bit CPUs.
