Subject: SATA Harddisk speed drop of 100 MB/s
Date: Thu, 21 Jun 2007 00:48:47 +0200 [thread overview]
Message-ID: <20070620224847.GA5488@alinoe.com> (raw)
hdparm -tT gives over 160 MB/s for my tripple 10k rpm Raptor RAID5
on 2.6.18, as expected.
In 2.6.22-rc5 this dropped to only 60 MB/s !
Is this a known issue?
I also measured it with bonnie; I get 108 MB/s reading speed on
2.6.18 and only 68 MB/s on 2.6.22-rc5.
