I notice that sometimes my backtest runs very quickly and the server statistics show >100% CPU usage, but other times it runs extremely slowly with <10% CPU usage.  This is for the exact same algorithm.  Is it because I am using a Community B-MICRO instance?  Or is it being bottlenecked when trying to load data?  Will subscribing to QC and getting a beefier backtesting node help with this?

Thanks,
Karthik
