well, I notice in that old thread, you did not explain how
your EC2 config differs from the 66% worse-performing "internal kit".
it's a claim that falls into the same category as cold fusion.
(not impossible, but would be silly to accept at face value.)

I'm pleased he reported the messy or embarassing bits. I prefer
to describe Compute Canada as a dotted line around drawn around
about 20 largely independent sites. some "sites" have a fairly
uniform user experience on multiple clusters, but most clusters
are a single, arbitrarily diverging cluster, at a single location.
in any case, it's a huge mess now (which is not to imply we're
not getting useful work done.)
so, any substantive comments about heterogenous loads on IaaS?
thanks, Mark Hahn.
