Hi folks,

is there something foul with RAIDframe, concerning system CPU time?
I have a directory with ~1000 entries on a RAID5, and a ls -l takes
30 seconds wall clock, of which 17 (!) seconds are system time, on
an otherwise only lightly loaded machine.  On a single disk of the
same type, the same thing completes in a tenth of a second.
Also, load average is always at least at 0.80+, even if the machine
is doing very little, and jumps up over 1.5 as soon as the RAIDs
get accessed (top etc. show almost no processes running during the
interval and display 80-100% time idle, so there seems to be something
odd with the load calculation aswell).
Has someone else experienced such things?  Is it normal for raidframe
to hog things? (the machine is performing well enough for its task,
but the thing with the abysmally slow directory listing+file stating
troubles me...)  This is on 1.5/i386, if it matters.
