howdy.
maybe this has been discussed in 'hackers' or elsewhere,
before - i can't find a reference via the search interface.
i'm a long time freebsd user, and i've been struck by how much my
systems (3 of them) have slowed down in its disk performance with
4.3-RELEASE, relative to 4.2-RELEASE and 4.1.1-RELEASE.
here is my data:
4.1.1-RELEASE, ASUS A7A mbd, wd600-b
(60gig udma100 drive).
time to newfs an 8192mby partition
('a' partition in the first slice): 8seconds.
4.3-RELEASE, same mbd/drive:
time to newfs the same 8192 mby
partition: 36seconds
this is 4.5x slowdown!
this 'newfs' is done by an express install in both
cases. even lowly linux-7.1 thinks this disk and system
are fast, and they zip along in comparison to 4.3-RELEASE.
i believe that a 4.2-RELEASE system would have the same
performance as the 4.1.1-RELEASE, based on my system
at work.
thoughts ?
