Trying to make agent clients on low end laptops like a Celeron 900, not a C++/GTK developer so was trying to do it with python, been brutal trying to build python wheels on the single core 900mhz cpu, might look into compiling on a stronger PC or just committing to C++/GTK. I was able to get it to work on an intel 270.
Python gets pretty heavy for old hardware. Once you hit your MVP you may want to look at compiled languages for better single-threaded perf.
