git clone https://github.com/eclipse/titan.core.git
cd titan.core
time make -j8

On Cygwin:

real    7m46.830s

On WSL Ubuntu:

by not doing the right thing. - Scott Meyers, An Effective C++11/14 Sampler
So if you're looking for a completely portable, 100% standards-conformant
way
to get the wrong information: this is what you want. - Scott Meyers
