Need for benchmarking
Use benchmarking tools to compare different implementations to the same problem. Proper benchmarking requires care. We need to guarantee a measurement won’t affect subsequent ones. For example, each measurement should run on a new process to make sure the data generated in the first measurement won’t affect the second one by triggering the garbage collector. We also need to make sure we warm up the code before each measurement, to make sure the VM won’t kick in dynamic code loading for some cases but not others. ...
