sharing some additional investigation i did today -- i manually wrapped the [`handleDidOpen()` function](https://github.com/microsoft/typescript-go/blob/62c88967c1a5402dbdc17c3d9ebd69fc376c8c24/internal/lsp/server.go#L278-L282) (LSP command `textDocument/didOpen`) with the pprof profiler and took a profile of an incremental update (opening...

@jakebailey just tried it out now (`Identifier: typescriptteam.native-preview`, `Version: 0.20250601.1`) at a high level the problem still persists, here are a subset of the logs after using go-to def on...

here's an updated `pprof` profile from `handleDidOpen()` -- the critical path seems to be dominated by updating file watchers (~15s) and visiting directories as part of `tryFindDefaultConfiguredProjectForOpenScriptInfo()` (5s). naively, both...

In case it's interesting to ya'll when testing on `tsconfig.all.json` the project load time is ~34s on a `64 GB memory, 8 vCPU` machine. The LSP consumes ~19.8 GiB of...

unsure if this is the same issue, however I work for a company with a large mono-repo containing many TS projects. one of our leaf projects contains a `Button` export...

I've chased the problem down to here: https://github.com/microsoft/TypeScript/blob/beb69e4cdd61b1a0fd9ae21ae58bd4bd409d7217/src/server/editorServices.ts#L4769-L4770 Our [_solution_ level `tsconfig.json`](https://www.typescriptlang.org/docs/handbook/project-references.html#overall-structure) contains the following config: ```json { "files": [], "include": [], "references": [ { "path": "..." }, { "path":...
