isolcpus=2,3 with 10 glx gears

cpu and ram speeds set to an integer 2:1  - might reduce any fractional clocking harmonics or jitter! ;-) kidding.

arm_freq=800
sdram_freq=400
core_freq=400
gpu_freq=300

I've left overnight 10 glx gears and two windows of 1080p YT vids going.

I need heavy rain after today!

6 glx gears all day
   

Started compiling vtk at 8:30 pm. See how we go in 16 gb...

Following Tchmiimy's approach on this page:

Success! I hope...
After 5 hours, there was still about 2000 files remaining to be built with ninja. (of just under 10000)
Code:
apt install -y build-essential mesa-common-dev mesa-utils freeglut3-dev ninja-build git cmake git clone --recursive https://gitlab.kitware.com/vtk/vtk.git mkdir build cd build cmake -GNinja -DVTK_WHEEL_BUILD=ON -DVTK_WRAP_PYTHON=ON ../vtk/ ninja python setup.py bdist_wheel

Then checking with python
Code:
cnc@bcm2711:~/devel/build$ python3 >>> import vtk >>> print(vtk.vtkVersion.GetVTKSourceVersion()) vtk version 9.1.0 >>> exit()

Now I just have to find where the wheel file is living
