[Xen-devel] 4.1.2 very slow without upstream patches, but fast with them, also 4.2 very slow

[Peter Maloney <peter.maloney@xxxxxxxxxxxxxxxxxxxx>]

my AMD FX-8150 system with vanilla source code is super slow, both the
dom0 and domUs. However, after I merge the upstream patches I found in
the openSUSE rpm, it runs normally.

I tried 4.2-unstable and it was the same. There was no rc1 when I tested
it about 1.5 weeks ago. And 4.2 has the same horrible performance, and
obviously those patches won't work any more since the 4.2 code looks
completely reorganized, so I'm stuck with 4.1.2

Here is the rpm I was using at the time:
http://download.opensuse.org/update/12.1/src/xen-4.1.2_16-1.7.1.src.rpm

To see the list of the patches and what order to apply them, see the
spec file.

Please make sure this performance issue is fixed for the 4.2 release.
And I would be happy to test whatever files you send me.
