Well, maybe not... Here's Windows wired to the network: C:\Users\Loren\Documents\Projects\Computing\BeagleBone Black\BBB Projects\1-Wire\OWFS Python logging>python ** non persistent : 42.48 ms, 43.65 ms, 44.34 ms, 44.82 ms, 47.53 ms, ** persistent : 38.35 ms, 39.17 ms, 40.23 ms, 41.67 ms, 42.80 ms, A bit better than Wi-Fi, but still slower than running everything on the BBB! I'd have expected results more like yours, with the external machine faster than testing from the little board: mnm @ razmaban:~/python$ python pyownet_timing.py ** non persistent : 3.18 ms, 3.24 ms, 3.24 ms, 3.25 ms, 3.47 ms, ** persistent : 2.37 ms, 2.39 ms, 2.40 ms, 2.42 ms, 2.58 ms, mnm @ vincent:~/M/_Linux/python/_mnms_tests$ python pyownet_timing.py //razmaban:4304 ** non persistent : 2.40 ms, 2.40 ms, 2.43 ms, 2.44 ms, 2.49 ms, ** persistent : 1.82 ms, 1.82 ms, 1.86 ms, 2.05 ms, 2.12 ms, One curiosity seems to persist in all configurations - each later test in the same sequence takes a bit longer! Guess I can't understand everything...
