Steve, you say you've been happy with XFS for a few years. Have you been using it under any kind of load?

Thanks for the numbers.

I didn't say I was happy with XFS. I said I don't use it and have heard horror stories about it.

Does anyone know the details as to the work that has gone on in recent kernel.org kernels regarding write barriers? Isn't it supposed to eliminate the need for turning hardware write caching off?
