I would guess that disk latency is the biggest bottleneck for zookeeper. Unless the SolrCloud install is quite large, I don't think that much is required in the way of CPU resources. If the ZK instances are not on dedicated hardware, you could ensure stellar performance by putting its database on one or more dedicated disks attached to a controller with battery backed (or NVRAM) cache.
