I have noticed that when I include things like CBOE and USEnergy data, e.g.
self.AddData(USEnergy, USEnergy.Petroleum.UnitedStates.WeeklyGrossInputsIntoRefineries).Symbol
self.AddData(CBOE, "VIX").Symbol
Then the backtest would become very slow, and (as a result??) it will be terminated after one-year worth of backtesting period. Anyone has this problem? What is the solution?

Hi pfchang !
Could you share a complete basic algorithm that reproduces the performance issue?
I created an github issue for a performance improvement we detected 3772 but it might not be the same issue.

Yes for example, there is a huge difference in calc time depending on whether the commented out block of code is or is not in effect. And it seems that
self.cboeVix = self.AddData(CBOE, "VIX").Symbol
would have caused the same issue.
Thanks Pfchang we fixed this issue.
