Surface Book 2 throttles excessively, often down to 0.4 GHz

I've recently purchased a 15" Surface Book 2.

When compiling large projects in Visual Studio 2017, I find that the processor often throttles excessively, often down to 0.4 GHz. As a result, compilation takes several times longer than it does on my 5 year old MacBook Pro. 

The Core Temp app shows that the CPU at this point is at 50-55 degrees Celcius or so.

The following question touched upon this problem, but the proposed solution did not work for me:

Any ideas on how to fix this?

Thanks.

    So it seems that 1903 has made it even worse. I am getting throttled down to .4ghz almost non-stop with lid closed using surface dock.

    Welp I updated to 1903 and the latest Surface Book 2 driver and firmware package that was just posted. Sad to say that the CPU is still throttling down to .4 GHz. That removes any and all hope that Microsoft would've fixed in the next Windows release / next Surface Book 2 firmware/driver update.
