I’m in the process of moving our core traffic from a local datacenter
to ec2, using haproxy for load balancing.

I am unable to get full usage of the 2 virtual cores. Previewed the
full traffic load today and hit cpu limits immediately. Initially,
with nbproc = 1, I see the first core is used at 100% utilization, the
second core remains completely idle.
