…pace workers (#11328) `Mutex` will block others requests. `RwLock` + `Arc` is faster. I asked ChatGPT about it: 🔒 So the Real Options Are: ✅ Arc<Mutex<Vec<WorkspaceWorker>>> Use this if: All accesses (read and write) are relatively balanced or infrequent. You want simplicity and don't expect much read contention. ✅ Arc<RwLock<Vec<WorkspaceWorker>>> Use this if: Most access is reading, and you want to allow multiple concurrent reads. Writes (e.g. adding/removing workers) are infrequent. In this case, RwLock may improve performance under heavy read concurrency (e.g., lots of requests querying the current workspace list).
