"That's just absurd. When you strip something of all context, you can make it mean anything you want regardless of what the original message was."
I suggested watching the video with the sound up first. And then turned down to remove the salesman's pitch and allow one to concentrate on the actual data being presented. Nothing absurd about that.
I administer point of sale and accounting servers that typically handle ~100 users or registers. And also servers which handle ~80 users NX desktops. Not one of them could benefit from > 4 thread write performance. More than anything, I might could use improved fs performance for 1 or 2 threads.

I don't really care how XFS might perform on hardware that will be available in 5 years time. I care what makes sense for our current hardware. In 5 years, we'll decide what FS is suitable for our new hardware at that time. And as always, I will consider XFS along with the other options. Just because it has never been quite suitable before does not mean that it can't be next time.
