Hello,
I wanted to know if there is a way to check how Lean is using the CPU power. Im running a core that Quantipian used one core, but QuantConnect using the B4-12 is using 332% of the CPU according to the backtesting stats.

Hi Giuliano,
The cores are preloading universe data, running a synchronization to get all the data in line, and then piping it to your algorithm methods. The data and algorithm work is done in parallel so that can ideally hit 1.5-2x CPU. The more CPU used the better (assuming the work is "good work").
Options universes have thousands of contracts and can use 800-2500% CPU (on purpose, by design).

Oh I get that. So lean will do parallelization automatically when possible?
