i saw that the performance in neovim (even with lua plugins and lua configs) is really bad in very large projects with a lot of files and a lot of lines of code for each file.
lsp server is going crazy. spikes the cpu and i cant even move. completion menu popup is really slow. typing is really slow.
how do i tell neovim to use more RAM, to allocate more memory to its resources (to allocate in advance, not to be limited to an amount of memory, for example max 1GB and also to tell to the language server to allocate more memory) to make overall performance really good.
