Corrigendum to “The IX Operating System: Combining Low Latency, High Throughput and Efficiency in a Protected Dataplane”

Abstract

On page 21 of “The IX Operating System: Combining Low Latency, High Throughput and Efficiency in a Protected Dataplane” we describe our use of the tool mutilate to evaluate the latency and throughput of memcached. We discovered an error in our setup: we did not load the initial key-value state into memcached before the start of the experiment. Instead, memcached started in an empty state, causing some GET requests to require less computation than intended. Table 1 shows the performance differences between our original and corrected memcached results.
