Subject: mdadm raid1 read performance
Date: Wed, 4 May 2011 01:07:45 +0100	[thread overview]
Message-ID: <BANLkTim8Ehn0fANtibg7X1cMVvOgt7CNMA@mail.gmail.com> (raw)

Hi,

I've been testing mdadm (great piece of software btw) however all my
test show that reading from raid1 is only the same speed as reading
from a single drive.

Is this a known issue? or is there something seriously wrong with my
system? i have tried v2.8.1 and v.3.2.1 without difference and several
benchmarking methods.

best regards,

Liam
