Don't forget that. ( what you have not quoted is the part that says that the fileset is 9GB. This is one of the busiest and most complex block-IO Linux systems i've ever seen, this is why i quoted it - the talk was about block-IO performance, and Stephen said that our block IO sucks. It used to suck, but in 2.4, with the right patch from Jens, it doesnt suck anymore. ) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
