Subject: CFQ I/O scheduler better than AS?

Hi:

I am sure that, for most people, the clear answer is "yes" (after all,
CFQ is the default I/O scheduler in Linux), but we are having serious
difficulties to find a benchmark which shows that CFQ is undoubtedly
better than AS.

We use several benchmarks and, in all of them, either AS is clearly
better than CFQ, or their performances are very similar.

Therefore, the question is, does such a benchmark exist?

Regards,

	Juan
