Does this support it/sec or sec/it?

Does this support it/sec or sec/it (it = iteration), similar to the Python tqdm package? Would be useful to calculate things like throughput.

you can add custom payloads to display any kind of data

Please add speed variable available for formatting or at least add .getDuration() so the speed can be easily implemented as a custom payload. It is especially helpful when total is unknown.
