Background indexing is too slow / demanding #1837

Open MahdiBM opened 1 week ago

Swift version

Swift 6.0.2 release

Platform

macOS 15

Editor

VS Code

Description

Background indexing looks to be 2-5x slower than Xcode's mechanism, and that's already a low bar to meet.

Perhaps we can have some benchmarks for sourcekit-lsp (through a package like ordo-one/package-benchmark), then we can both make sure that this doesn't regress any further, and also try to optimize it slowly but surely.

We'll need to discuss how to set up the benchmarking, if that's desirable.

Steps to Reproduce

Enable background indexing on a big-enough project.
