How to get sampling time of Metropolis Hastings algorithm

Hello,

I have a quick question regarding how to get sampling time when we use Metropolis Hastings algorithm. When we used ‘NUTS’, I found that we can use ‘process_time_diff’, ‘perf_counter_diff’,’ or perf_counter_start’ to get the time it needed for each sampling. Are there similar options when we use Metropolis Hastings algorithm? I can’t seem to find it at the documentation here (‘Inference — PyMC3 3.11.5 documentation’).
