Subject: Combined mode quirk removal kills performance
Date: Thu, 31 May 2007 09:45:29 -0500 [thread overview]
Message-ID: <465EDF89.9050207@tuxrocks.com> (raw)
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
The patch to "remove combined mode quirk" (git bisect says
8cdfb29c0cd8018f92214c11c631d8926f4cb032) makes my laptop run slower
than a dead sloth. "hdparm -T" indicates that buffered disk reads on my
hard drive drop from 48-50 MB/sec to 1-2MB/sec, and the system is nearly
unusable.
System is a Dell Inspiron E1705 (Core 2 Duo 2.16GHz) running x86_64 FC6.
