Hi guys, I have an x86 question that I really hope you can help with: Running the kvm-unit-tests on x86, I see a quite large difference between I/O from the kernel, and I/O user (around 6,000 cycles) on two separate platforms. This is probably expected, but what is the explanation? If I correlate with system call overhead from lmbench, it's nowhere near that (in the hundreds of cycles), so I'm sure I'm missing something obvious. Thanks! -Christoffer -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
