Well, it took just 4 seconds to backtest a simple CCI system using 6 and a half years of 1-minute data. 64-bit version is even faster. RoundLotSize was set to 0 here. So you see contracts with comma. Forgot to set it to 1. But that doesn't matter for the speed test. Also the different position size in comparison to the low one of the MC backtest doesn't matter here.
