Is there a benchmark performance test to reveal how the disk's iops effect zookeeper's tps/qps?

As the document says
"incorrect placement of transasction log
The most performance critical part of ZooKeeper is the transaction log. ZooKeeper syncs transactions to media before it returns a response. A dedicated transaction log device is key to consistent good performance. Putting the log on a busy device will adversely effect performance..."
However, is there a benchmark perf test to reveal how the disk's iops effect zookeeper's tps/qps?

For public benchmark:
* ZK has a systest in src/java/systest.
* Checkout https://coreos.com/blog/performance-of-etcd.html. There is a
github link on the benchmark.

If you end up writing your own benchmark, please consider contribute it
back to open source :)
