IMHO anyone complaining about time taking for dependency resolution etc. They should spend THEIR time writing stuff in a real native language for speed. The difference I see with jem[1] vs java-config, is ridiculous. Sometimes I merge hundreds of java packages. All those milliseconds add up. Not to mention resources, ram, CPU, and all drains your battery... If aspects of portage were done in C or C++, or maybe even Go. There would be substantial performance improvements. The existing python code can remain. Python can load and call functions from C/C++ DSO. And vice versa, calling Python code from C/C++. I would say C vs C++ but that is up to others. Put my time where my mouth is... Well I did, its called jem. What is jem? Its java-config ported to C. I would be looking to port more of Gentoo's tools to C for longevity and speed. Not speed of development, but speed for everyone else. Instead I am doing C for other projects. 1. https://github.com/Obsidian-StudiosInc/jem P.S. jem does need a bit more work to replace java-config entirely. Its designed to not be Gentoo specific. There is little interest from Gentoo, much less outside. Thus its more a case study than anything benefiting anyone including myself. I will further it as I have interest and time permits. Still have a few more defects to address. -- William L. Thomson Jr.
