Slackware 14.1 x64
Xen 4.4.0
Lilo + either kernel:
Kernel 3.10.17 using default Slackware 14.1 'huge' config -
ftp://ftp.slackware.com/pub/slackware/slackware64-14.1/source/k/config-x86_64
Kernel 3.14.13 using Slackware-current (July 23 2014) 'huge' config -
ftp://ftp.slackware.com/pub/slackware/slackware64-current/source/k/config-x86_64
Making this system a Dom0 results in poor & slow video performance.
Video performance without Xen is normal. Haven't yet determined
whether the video problem could be a symptom of some other general
system performance issue when running Xen. Xen kernel differs from
the original kernel only in that mbootpack (
http://www.tjd.phlegethon.org/software/ ) was used to put kernel +
initrd + xen together and prerequisite Xen config options were added
per http://wiki.xenproject.org/wiki/Mainline_Linux_Kernel_Configs :

The resulting video symptoms occur even with no DomU's running and
with xencommons + xendomains stopped -
Before starting X while working with console tty's there is ~1 second
lag for screen to fully redraw whenever switching between tty's.
example - going back and forth via Alt-F1 and Alt-F2 results in a
noticeable delay before all text is redrawn on the screen.
While in X with only Firefox running, youtube/flash videos are
unwatchable especially in full screen, video frames not drawing
quickly enough, ends up looking like a flip book of images with some
frames missed and the rest going slowly, also leads to Firefox
response lag while in full screen, same even at low quality 240p.
Full screen videos in mplayer look decent until trying 1080p at which
point things become unwatchable and again video appears to be not
drawing/refreshing quickly enough to keep up, gets hit with the slow
flip book effect.
Tried with no improvement:
kernel 3.15.x
disabled hyperthreading per
http://wiki.xen.org/wiki/Tuning_Xen_for_Performance#Hyperthreading_in_Xen_4.3_and_4.4
booting with _iommu_=_no-snoop_
updated BIOS to 1.21
vga=0x35A
adding the following to /etc/X11/xorg.conf:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
More system info follows, any suggestions would be most appreciated.
Thanks in advance.

hdparm is roughly the same with non-xen kernel vs xen kernel
hdparm -tT /dev/sda
/dev/sda:
