I only posted data from half of one of these tests here because it was the only one that I found that both had noticeable overhead in the filesystem code. It also showed substantial, consistent, and measurable deltas between the different filesystems. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
