Subject: [xen-unstable PATCH] x86: Increase the default NR_CPUS to 256
Date: Mon, 29 Aug 2011 12:41:59 +0200 [thread overview]
Message-ID: <4E5B6CF7.3050304@redhat.com> (raw)
Changeset 21012:ef845a385014 bumped the default to 128 about one and a half years ago. Increase it now to 256, as systems with eg. 160 logical CPUs are becoming (have become) common.
Thanks for considering.
