You can use the cpu cgroup controller to starve your program of CPU time. Use the cpu.cfs_quota_us and cpu.cfs_period_us knobs. Now if only there was a way to use the blkio controller to emulate the performance characteristics of spinning rust (reasonable sequential IO performance but with a big penalty for random access...)
