I have the same experience, if that helps :(.

And my images is not any where near that size, only 463MB!

Using Heat, creating a volume for each instance on a remote SAN,
'takes ages' (haven't clocked it, but creating eight instances
takes well over half an hour)!


I'm "fairly" certain that it's not the network - I have four
trunked 1Gbps links directly down to my storage (and I've triple
checked that that is used).


I've had other things on my mind and I'm not creating a lot of
instances now that most of them have been created, but I've always
intended to go back to this problem so I'm going to follow
this thread closely.
