Hi Qian, I can give you an example of one of our systems that uses zookeeper (crawling for our Yahoo! search engine). It has of the order of 4K clients - expecting to grow to 8K to 12K. Their write load is around 100 writes/sec (this is pretty low) and 4K reads/sec (max reads) with an ensemble of 5 zookeeper servers.
Hope this helps. What kind of workload are you expecting?
