Looks good. Our default used to be --thread-pool-size=64. But we changed
it to using no thread pool because on lower end of workloads it performed
better. When multiple threads are doing parallel I/O then, thread pool
helps. So people who want to do lots of parallel I/O should manually
enable thread pool.
