Kent, I tried that, only for me it worked doing "iozone 160". Here is
my results:
11483869 bytes/second for reading
15155142 bytes/second for writing
Is that really slow? It's nowhere near 33MB/second. I have a Maxtor
7000rpm with UDMA66 capabilities, although I'll have to wait for -STABLE
to support that, and a new motherboard as well. I may recompile with
the old flags just to see the difference.
Happy New Year (why am I sitting at this computer 8-) )!
Joseph
