Subject: SSD and IO schedulers
Date: Fri, 30 Jan 2009 22:55:47 +0100 [thread overview]
Message-ID: <4dcf7d360901301355l7ed26a5aob7ef6d79d9607b6b@mail.gmail.com> (raw)
Hi, I was wondering how IO schedulers such as as-iosched, deadline and
cfq behave on SSD
(that have virtually no seek time), from a theoretical point of view.
How do they affect
performance on these devices?
I heard that the noop scheduler is often chosen by owners of EeePcs
(with a SSD unit).
They report superior performance by using this (quite simple) scheduler.
Are there any scientific benchmarks around?
