My build tool spat out a 700MB compile_commands.json file, which the C++ language server turned into 25k files. None of the language server implementations were able to process even a go to file on the code.

it takes about 15 minutes for Visual Studio (well, visual assist) to generate the index for the project, and then the navigation is instant. I've tried a few times over the last few years with various language server and clients, and my experience has been the same pretty much every time.

You can use ctags/cscope to handle that, FWIW languages like C and C++ have a massive toolset built around Vim, so even for the most obscure use case, I'm pretty sure there will be a way.
