Did some more testing. I turned off hyperthreading in the BIOS. This seems to improve performance but is not optimal:

Cinebench results were 15% lower.

I also tested this on cAlgo 2.0 (Public beta). Same results.

Limitation of Ctrader

It looks like Ctrader does not scale very well with a lot of cores.

Running on 8 cores looks fine:

But as you can see on 16 cores it starts to fall off:

It looks like there is a limitation where only 8 cores can be fully used. More cores will just spread the load but not improve performance.

Is there any chance on an update to improve the handling of more cores and more cpu's?

For reference, below the utilization when running Cinebench R15:

RE:

When I run 6 instances of the optimizer at the same time I have no problem maxing my CPU usage at all (see below). Please let me know if I can fix this and how, or if you can fix this. For me the Ctrader platform is not very productive if I am unable to backtest/optimize at proper speeds.
