From 97453a90779dad29e45ce244f4e7886ca6e686ca Mon Sep 17 00:00:00 2001 From: Tunglies <77394545+Tunglies@users.noreply.github.com> Date: Tue, 20 Oct 2026 16:58:28 +0800 Subject: [PATCH] perf(tray): build menu in one main-thread dispatch Every tauri menu API call from a non-main thread blocks on a synchronous round-trip to the app event loop. Building the tray menu with proxy groups enabled issued one such round-trip per menu item (200+ for a typical subscription) while holding the menu update lock, and the cost grows when the event loop is busy with webview work. Gather the async inputs (verge/clash/profiles snapshots and the proxy view) on the caller's task, then construct every menu item inside a single run_on_main_thread closure and hand the finished menu back; set_menu and the per-group refresh keep their original call sites. Measured on a standalone tauri bench (5 groups x 40 nodes): a rebuild drops from ~6.2ms to ~1.6ms on an idle event loop and from ~11.4ms to ~1.6ms with the loop busy. refresh_proxy_items already used this shape; the rebuild path now matches it. --- src-tauri/src/core/tray/mod.rs | 126 ++++++++++++++++++--------------- 1 file changed, 67 insertions(+), 59 deletions(-) diff --git a/src-tauri/src/core/tray/mod.rs b/src-tauri/src/core/tray/mod.rs index 221f23aa1..d2cb186af 100644 --- a/src-tauri/src/core/tray/mod.rs +++ b/src-tauri/src/core/tray/mod.rs @@ -1,4 +1,4 @@ -use crate::config::{IProfilePreview, IVerge};
