From 613bf8e2d7a7dc434b9baeffc372c32b8a413d0a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alejandro=20G=C3=B3mez?= Date: Fri, 16 Jan 2026 17:14:15 +0100 Subject: [PATCH] perf: Add progressive batched relay connections for inbox sync MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements a progressive batching strategy for connecting to inbox relays, preventing the browser from being overwhelmed by concurrent AUTH requests and relay subscriptions. ## Problem When enabling inbox sync, the app would: - Connect to ALL inbox relays simultaneously (could be 5-10+ relays) - Each relay potentially requires AUTH (signing an event) - All AUTH requests happen concurrently - Browser becomes unresponsive during initial sync - Poor UX with hanging/freezing during connection phase Example: User with 8 inbox relays → 8 concurrent connections → 8 AUTH signatures at once → browser hangs for several seconds ## Solution ### Progressive Batched Connection Strategy **Initial Batch** (Immediate): - Connect to first 3 relays right away - Get messages flowing quickly from primary relays - Users see messages within seconds **Subsequent Batches** (Delayed): - Connect to remaining relays 2 at a time - 1.5 second delay between batches - Allows AUTH requests to complete before next batch - Browser stays responsive throughout **Example Timeline**: ``` T+0s: Connect to relays 1-3 (batch 1) T+1.5s: Connect to relays 4-5 (batch 2) T+3.0s: Connect to relays 6-7 (batch 3) T+4.5s: Connect to relay 8 (batch 4) ``` ### Configuration ```typescript const INITIAL_BATCH_SIZE = 3; // First batch (immediate) const BATCH_SIZE = 2; // Subsequent batches const BATCH_DELAY_MS = 1500; // 1.5s between batches ``` ### Implementation Details **Before**: ```typescript // Connected to ALL relays at once pool.subscription(allRelays, [filter], { eventStore }) ``` **After**: ```typescript // Batch 1: First 3 relays (immediate) pool.subscription(firstBatch, [filter], { eventStore }) // Batch 2+: Remaining relays (delayed) setTimeout(() => { pool.subscription(nextBatch, [filter], { eventStore }) }, batchNumber * BATCH_DELAY_MS) ``` ## Performance Impact **Before**: - ❌ Browser freezes during AUTH burst - ❌ Delayed initial message display (waiting for all relays) - ❌ Poor perceived performance **After**: - ✅ Browser stays responsive - ✅ Messages appear within seconds (from first batch) - ✅ Smooth progressive loading - ✅ AUTH requests spread over time - ✅ Better perceived performance ## Additional Improvements - Converted remaining console.log to dmDebug/dmInfo/dmWarn - More consistent debug logging throughout gift-wrap service - Better visibility into batching progress ## Testing - ✅ All 864 tests pass - ✅ Build succeeds with no errors - ✅ Batching logic verified - ✅ Progressive connection strategy confirmed ## Files Changed - `src/services/gift-wrap.ts` - Implemented progressive batching Co-Authored-By: Claude Sonnet 4.5 --- src/services/gift-wrap.ts | 119 ++++++++++++++++++++++++++++---------- 1 file changed, 89 insertions(+), 30 deletions(-) diff --git a/src/services/gift-wrap.ts b/src/services/gift-wrap.ts index 2d17a9a..3706301 100644 --- a/src/services/gift-wrap.ts +++ b/src/services/gift-wrap.ts @@ -353,8 +353,9 @@ class GiftWrapService { ?
