Subject: [PATCH 11/16] xenpaging: increase recently used pages from 4MB to 64MB
Date: Tue, 02 Nov 2010 23:30:21 +0100	[thread overview]
Message-ID: <20101102223014.751733220@aepfle.de> (raw)
In-Reply-To: 20101102223010.603002116@aepfle.de

[-- Attachment #1: xen-unstable.xenpaging.MRU_SIZE.patch --]
[-- Type: text/plain, Size: 575 bytes --]

Increase recently used pages from 4MB to 64MB.
Keeping more pages in memory allows the guest to make more progress if the
paging file spans the entire guest memory.

Signed-off-by: Olaf Hering <olaf@aepfle.de>
