Abstract
Conventional wisdom holds that storage is not a big contributor to application performance on mobile devices. Flash storage (the type most commonly used today) draws little power, and its performance is thought to exceed that of the network subsystem. In this article, we present evidence that storage performance does indeed affect the performance of several common applications such as Web browsing, maps, application install, email, and Facebook. For several Android smartphones, we find that just by varying the underlying flash storage, performance over WiFi can typically vary between 100% and 300% across applications; in one extreme scenario, the variation jumped to over 2000%. With a faster network (set up over USB), the performance variation rose even further. We identify the reasons for the strong correlation between storage and application performance to be a combination of poor flash device performance, random I/O from application databases, and heavy-handed use of synchronous writes. Based on our findings, we implement and evaluate a set of pilot solutions to address the storage performance deficiencies in smartphones.
