I don't believe even with Ansible's accelerated mode it can come anywhere close to Salt for large deployments. It is still agentless and has to run from a single source and using ssh which is going to be slower than 0MQ. Also using something like salt-syndic to create topologies can reliably scale to thousands of machines and still cope with the load.
