That's still happening but it's Sublime Texts fault for a bad API. It is fixed in the current development branch though (ST4). 

The problem is workspace symbols. For my project there are 40k symbols (system SDKs I like to browse easily) which translates to 10MB of JSON text.

It's so stupid it makes my feel ill and I weep for my CPU. I'm going to submit an issue to Microsoft since they at least allow this on GitHub.

I've been talking to the LSP people at ST and they tell me it's really common for servers to be written in JavaScript because it's easily supported within VSCode's architecture (which Electron I'm sure you know). They may have written the thing in JavaScript for all I know. That's a problem right there as far as performance is concerned.
