Subject: Testing of Ingo/Arjan highpte on 16-way NUMA-Q
Date: Thu, 28 Mar 2002 14:48:37 -0800	[thread overview]
Message-ID: <162960000.1017355717@flay> (raw)
In-Reply-To: <20020326191814.F13052@dualathlon.random>

Adding your highpte patches to the NUMA-Q seems to make no
performance impact whatsoever (just doing kernel compile). The
profiles are so similar, it almost looks like it's not doing anything at
all ;-) I find this a little strange, as all my ZONE_NORMAL is on
node 0, so I'd expected this to have some sort of impact (either 
positive or negative ;-)). 

Is there an easy way to test whether this was working or not?

Thanks,

M.

PS. yes I did remember to turn on the 4G-highpte option ;-)
