Tom Weininger c1ebe18e2a Add cpu-pinning element ... The new "cpu-pinning" element optimizes the amphora image for better vertical scaling. When an amphora flavor with multiple vCPUs is configured it will configure the kernel to isolate (isolcpus) all vCPUs except the first one. Furthermore, it uninstalls irqbalance and sets the IRQ affinity to the first CPU. That way the other CPUs are free to be used by HAProxy exclusively. A new customized TuneD profile applies some more tweaks for improving network latency. This new feature is disabled by default in diskimage-create.sh.
