Heavy memory usage

[allsey87]

rust-analyzer version: 0.3.1850-standalone

rustc version: 1.78.0-nightly (8ace7ea1f 2024-02-07)

relevant settings: Using linkedProjects in vscode to specify two projects, a workspace with 4 members and a standalone crate.

Rust analyzer is idle at the moment, however, it is consuming nearly 20% of system memory (24 GB + 1 GB swap), that seems... excessive :D

How large are the projects? How many and how large are the dependencies (e.g. how many lines does Cargo.lock have)?

[allsey87]

The Cargo.lock file for the workspace has 4600 lines, while the standalone crate outside of the workspace has 900 lines.

4.5G don't seem abnormally much for two projects of that size, so I think this is a duplicate of #7330.
