Subject: AS performance with reiser4 on 2.6.3
Date: Thu, 26 Feb 2004 09:48:10 -0800 (PST)	[thread overview]
Message-ID: <200402261748.i1QHmJE12429@mail.osdl.org> (raw)

Hi Nick,

I started getting some results with dbt-2 on 2.6.3 and saw that reiser4
is doing a bit worse with the AS elevator.  Although reiser4 wasn't
doing well to begin with, compared to the other filesystems.  I have
links to the STP results on our 4-ways and 8-ways here:
	http://developer.osdl.org/markw/fs/dbt2_stp_results.html

I noticed that __preempt_spin_lock was near the top of the profile and
about 2 times higher the with AS, compared to deadline.

I'm going to run through the other filesystems to see how the elevators
affect them.
