OK. The changes in the lower right window show, that there is still successful
write request processing...

OK - gmirror was not the cause... :) But since gmirror had a quite high "ms/r"
value, it might be, that graid5 isnt the real cause, too (maybe ur box just
cant take so many simultaneous read requests)...
Unfortunately I removed some debug code. I inserted it now. It would be nice,
if u could upgrade to the newest version of graid5 (some minutes old)... Then
debug level 2 should produce more output (each read/write request gets two
lines: start and done)... :-)
