This document analyzes the performance of Docker containers running varying I/O intensive MySQL workloads. Key metrics like I/O entries, size, CPU utilization, and read/write ratios were collected from blktrace, blkparse, and iostat. The analysis found these metrics began saturating after 3 containers, indicating the default system cache was effectively handling redundant data between containers. While Docker performed well, a cache designed specifically for containers may further boost performance, especially with large numbers of identical containers.
