Wow crazy. I honestly couldn't say what lsp settings I use. My personal config broke a while back and I use Astronvim now until I get to fixing it... Although so far its been good enough that I just dont bother moving back...
Yea, for me it's also working pretty fast (unused ram is wasted ram anyway), just that I must always keep an eye on my RAM usage of my 10-year-old PC with 8GB of RAM and HDD only...
