Description

https://github.com/rust-lang/rust-analyzer/issues/11325 might not cover everything that should be in such a chapter/section, but has an excellent title at least.

For content, I'd want to see information about what features tend to eat lots of RAM or CPU, how to measure it (if rust-analyzer doesn't die immediately), and suggestions on how to deal with this (disabling features, tuning limits, rearranging code, reducing macro output size, attempting to redesign aspects of rust-analyzer, or any other thing).

Document resource-intensive features, ways to measure RAM and CPU use, and practical mitigations; the work is done when the manual has a useful, complete chapter or section covering those topics.
