IO Workload Characterization Of Tizen Based Consumer Electronics

Abstract

In this work, we explore IO characteristics of the Tizen based smartphone to provide insights for optimizing the IO performance and the IO system design in Tizen based Consumer Electronics. Summary of our findings are as follows: 90% of all write IOs are synchronous, 75% of all write accesses are by SQLite, 85% of all IOs are random accesses, and 90% of all writes are in synchronous IO mode. RUA (Recently Updated Application) manager, which is called at the beginning of every application, generates 18 write IOs to update rua.db file.
