> In running a YCSB workload, I managed to DDOS a DNS server since it seems to
> be flooding lots of DNS requests. Installing nscd on the client machines
> improved throughput by a factor of 6 and stopped killing the server. These
> are long-running clients, so it's not clear why we do so many lookups.
