And not even that -- this refers to file system performance. Which means the majority of your hard disk activity (swapping) isn't affected at all. As with virtually all filesystem speed impacts, the scenarios most affected will be those that generate a lot of metadata writes. Most single-user usage patterns aren't impacted. (On the other hand, most single-user usage patterns have the least to benefit from a JFS, but that's only fair. :-)
