How scalable is the benchmark?
There is no hard limit in the benchmark harness and the work load when it comes to scaling up the number of benchmark threads and this has been verified in the testing. The size of the workload does increase with the number of benchmark threads. While some workloads are embarrassingly parallel and will scale well long past the 64 benchmark threads it has been verified with, others intentionally introduce scalability problems, for example with using java locks and also by heavy work which introduces several scalability problems, in the hardware and on the memory bus, as well as in the JVM with heavy allocation as well as large-scale garbage collection work.
