Some compilers take a long time to achieve the performance they're currently at, and many engineers. I'm soloing a runtime similar to an existing one with the goal of matching or beating the performance, right now I'm beating on memory usage alone, the "months" is only because I'm not investing more than the weekly tokens Claude will give me for $100 a month, plus dividing it out of my other projects I use Claude for.

I looked at a similar project to mine, done by someone for several years now, they're working 100% solo, I'm already where they're at, with several things they don't yet have.
