With the progress of server consolidation, we tend to operate important applications (APs) and normal APs in the same server. The important APs need the real-time performance and IO performance strictly. In this presentation, I propose the resource optimized method which predicts I/O throughput and latency with regression analysis and feedback function. I evaluate Linux/cgroups in latency and IO throughput with fio benchmark. This method can optimize the computing resources according to each AP requirement.
