At the same time, I think that the workloads where the filesystem matters the most are the ones that access the disk. With computers, in a large percentage of the time that people notice themselves waiting, it is the disk drive they are waiting on. Sigh, there are so many things we should optimize for, and it will be years before we have hit all the important ones. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
