[Openstack] Slow Horizon on Icehouse.

Hey, all. I've got an Openstack install, with each control node on its
own 24 GB, quad-core system. And yet my Horizon is really quite slow;
I've seen it take 15+ seconds to log in, click on the "routers" tab,
The only host among the control nodes that showed significant pain was
the MySQL host; I replaced its SATA disk with an SSD last night, and now
instead of a load average ~1.65, it's now around 0.10. And things feel
marginally better, but it's still darn slow, so I'm guessing the primary
bottleneck was *not* MySQL.
Any suggestions on what I should be digging into? Logs in the cloud
controller box? Known API bottlenecks?
