- Use only steady timestamp counters to guarantee correctness - CPU backend: directly measure total hashrate using raw hash counters from each thread; update data more often on ARM CPUs because they're slower - GPU backends: directly measure total hashrate too, but use interpolator with 4 second lag to fix variance from batches of hashes Total hashrate is now measured directly (realtime for CPU, 4 seconds lag for GPU), so it might differ a bit from the sum of all thread hashrates because data points are taken at different moments in time. Overhead is reduced a lot since it doesn't have to go through all threads to calculate max total hashrate on every timer tick (2 times a second).
