> Debug switches? Irrelevant, as 7.2 performed just as poorly (if not worse)
> in the threaded random writes test. One would think that the unrealistically
> poor [disk?] I/O performance bench data in FreeBSD was just a glitch, but
> using the OS everyday as a workstation, I actually notice that there could
> be some truth in those numbers. At least for ATA, when there's some disk I/O
> going on, file write operations that normally take milliseconds, may take
> tens of seconds or a minute! For example, loading the root disk with some
> serious concurrent I/O (portupgrade, find, tar xz, etc) makes opera
> unusable: the web browser normally saves "sessions" file everytime there's
> a change (e.g., a tab closed, or a page scrolled), and usually the write
> operation is unnoticeable, but with heavy disk I/O, one could wait for tens
> of seconds before, say, a page gets scrolled following keyboard input.

> I thinks that stream [memory benchmark] may also be demonstrating a
