Subject: asynchronous commit feature
Date: Thu, 23 Aug 2007 09:09:00 -0400
Message-ID: <b42b73150708230609m4c48f7eel6aa92db4e1f10b13@mail.gmail.com> (raw)

I'm testing the new asynch commit feature on various raid
configurations and my early findings is that it reduces the impact of
keeping wal and data on the same volume.  I have 10 disks to play
with, and am finding that it's faster to do a 10 drive raid 10 rather
than 8 drive raid 10 + two drive wal.

anybody curious about the results, feel free to drop a line.  I think
this will be a popular feature.
