Subject: raid5 write performance
Date: Sun, 2 Jul 2006 17:02:58 +0300 [thread overview]
Message-ID: <5d96567b0607020702p25d66490i79445bac606e5210@mail.gmail.com> (raw)
Neil hello.
I have been looking at the raid5 code trying to understand why writes
performance is so poor.
If I am not mistaken here, It seems that you issue a write in size of
one page an no more no matter what buffer size I am using .
1. Is this page is directed only to parity disk ?
2. How can i increase the write throughout ?
Thank you
