Hello,

I recently ran some tests on a quad core machine.  I received my output, and there were two sample counts and two sample percentages.  I did some reading and realized that the duplication was due to having multiple cores.  However my question is why am I only seeing two if I have 4 cores?

And excerpt from the output can be seen below.

Second question is what does the no-vmlinux symbol represent?

Thank you,

-Craig
