The lustre zpios-test simulates a reasonable lustre workload. It will create 128 threads, the same as a Lustre OSS, and then 4096 individual objects. Each objects is 16MiB in size and will be written/read in 1MiB from a random thread. This is fundamentally how we expect Lustre to behave for large IO intensive workloads.
