Single core CPUs may be rare but single core VMs probably represent the dominant number of deployments out there as it's much more efficient scheduler wise to go with more single CPUs than fewer multi CPU VMs. Not that I have any problem running multithreaded apps on a single CPU, I do it all the time. It is kind of unconventional using a load balancer to spread load specifically for optimal hypervisor scheduling though(traffic is load balanced regardless). nate
