Perhaps network throughput where the snapshot is hosted (The controller node)?

Subject: [Openstack] launching multiple VMs takes very long time

if I launch one vm at a time its doesnt very long to start up the instance. maybe a minute.
if I launch 4 instances (of the same snapshot as before) it takes 30 minutes.

they are all launching to different compute nodes, the controllers are all multicore, I dont see any processes on the compute nodes taking much cpu power, the controller has a keystone process mostly sucking up 1 core, loads and loads of beam.smp from rabbitmq but none are really taking any cpu time.

the glance image storage is on the controller node, the snapshots are 2-3G in size.

where should I start looking to find out why things are so slow?

thanks
