Thanks... I actually got all the feedback I needed privately.
The basic problem was that a single "cpu" in an ontario isn't fast
enough to sustain the packet rates required for 10GbE, even using
jumbo frames (~135Kpps).
I do have one outstanding question: When using dtrace to profile
a problem like this, I was using the following dtrace script:
#!/usr/sbin/dtrace -s
profile:::profile-997
{
@a[stack(20)]=count();
}
END
{
trunc(@a, 20);
printa(@a);
}
It seem to sort of "randomly" pick a CPU to run on:
CPU ID FUNCTION:NAME
27 2 :END
unix`disp_getwork+0x88
unix`idle+0xd4
unix`thread_start+0x4
<...>
Is there a way to bind this to a CPU so I can watch
the CPU that my ithread is running on?
