# 🚀 PERFORMANCE OPTIMIZATION PLAN - TIVIMATE PARITY
|
||||
|
||||
**Goal:** Achieve TiviMate-level performance across all areas
|
||||
**Date:** March 25, 2026
|
||||
**Total Issues Found:** 23 issues (3 critical, 6 high, 8 medium, 6 low)
|
||||
|
||||
---
|
||||
|
||||
## 🎯 QUICK WINS (Hour 1-2)
|
||||
|
||||
### P0-1: Fix EPG N+1 Query Storm
|
||||
**Impact:** 50-200 concurrent requests → 1 bulk request
|
||||
**File:** `lib/features/iptv/widgets/mobile_live_tv_tab.dart:556`
|
||||
|
||||
**Current:** Each channel card calls `getShortEPG()` individually
|
||||
```dart
|
||||
// BAD - Fires 50+ concurrent requests
|
||||
for (Channel channel in channels) {
|
||||
final epg = await service.getShortEPG(channel.streamId);
|
||||
}
|
||||
```
|
||||
|
||||
**Fix:** Batch EPG fetching
|
||||
```dart
|
||||
// GOOD - 1 request for all channels
|
||||
final epgData = await service.getBatchEPG(channelIds);
|
||||
```
|
||||
|
||||
**Expected Impact:** -80% network congestion, -90% jank
|
||||
|
||||
---
|
||||
|
||||
### P0-2: Remove Destructive Cache Clearing on Startup
|
||||
**Impact:** 5-20s saved on each app launch
|
||||
**File:** `lib/main.dart:31`
|
||||
|
||||
**Current:** Deletes entire cache on every startup
|
||||
```dart
|
||||
await Hive.deleteBoxFromDisk('dio_cache'); // BAD
|
||||
```
|
||||
|
||||
**Fix:** Implement TTL-based invalidation
|
||||
```dart
|
||||
// GOOD - Cache lives for 1-6 hours
|
||||
if (cacheExpired(lastRefresh, duration: Duration(hours: 1))) {
|
||||
await refreshCache();
|
||||
}
|
||||
```
|
||||
|
||||
**Expected Impact:** -80% startup time on cold launches
|
||||
|
||||
---
|
||||
|
||||
### P0-3: Preserve Tab State with IndexedStack
|
||||
**Impact:** Instant tab switching, preserved scroll position
|
||||
**File:** `lib/features/iptv/screens/mobile_dashboard_screen.dart:33`
|
||||
|
||||
**Current:** Creates new tab widget on every switch
|
||||
```dart
|
||||
// BAD - Tab destroyed, all data lost
|
||||
switch (currentIndex) {
|
||||
case 0: currentTab = MobileLiveTVTab(...); break;
|
||||
}
|
||||
```
|
||||
|
||||
**Fix:** Use IndexedStack to keep tabs alive
|
||||
```dart
|
||||
// GOOD - All tabs stay alive in memory
|
||||
IndexedStack(
|
||||
index: currentIndex,
|
||||
children: [
|
||||
MobileLiveTVTab(playlist: widget.playlist),
|
||||
MobileMoviesTab(playlist: widget.playlist),
|
||||
// ...
|
||||
],
|
||||
)
|
||||
```
|
||||
|
||||
**Expected Impact:** Instant switching, zero data loss
|
||||

|
||||
|
||||
## 🔧 CORE FIXES (Hour 2-4)
|
||||
|
||||
### P1-1: Debounce Search Input
|
||||
**Impact:** Eliminate per-keystroke rebuilds
|
||||
**File:** `lib/features/iptv/widgets/mobile_live_tv_tab.dart:40`
|
||||
|
||||
**Current:** setState on every keystroke
|
||||
```dart
|
||||
// BAD - Full rebuild on each character
|
||||
_searchController.addListener(() {
|
||||
setState(() { _searchQuery = _searchController.text; });
|
||||
});
|
||||
```
|
||||
|
||||
**Fix:** Use debounce (500ms)
|
||||
```dart
|
||||
// GOOD - Only rebuild after 500ms of inactivity
|
||||
_searchDebounce = Timer(Duration(milliseconds: 500), () {
|
||||
setState(() { _searchQuery = _searchController.text; });
|
||||
});
|
||||
```
|
||||
|
||||
**Expected Impact:** -95% search-related jank
|
||||
|
||||
---
|
||||
|
||||
### P1-2: Image Cache Size Limits
|
||||
**Impact:** -50% memory usage, faster scrolling
|
||||
**Files:** Multiple `CachedNetworkImage` usage
|
||||
|
||||
**Current:** No size limits
|
||||
```dart
|
||||
// BAD - Downloads full resolution (could be 1000x1500px)
|
||||
CachedNetworkImage(imageUrl: url)
|
||||
```
|
||||
|
||||
**Fix:** Set appropriate display sizes
|
||||
```dart
|
||||
// GOOD - Resized to 100x150 display size
|
||||
CachedNetworkImage(
|
||||
imageUrl: url,
|
||||
memCacheWidth: 100,
|
||||
memCacheHeight: 150,
|
||||
maxHeightDiskCache: 150,
|
||||
maxWidthDiskCache: 100,
|
||||
)
|
||||
```
|
||||
|
||||
**Expected Impact:** -60% cache size, -40% memory
|
||||
|
||||
---
|
||||
|
||||
### P1-3: Fix Double FocusNode Disposal
|
||||
**Impact:** Eliminate crash on player exit
|
||||
**File:** `lib/features/iptv/screens/native_player_screen.dart:458`
|
||||
|
||||
**Current:** Disposes FocusNodes twice
|
||||
```dart
|
||||
// BAD - Double disposal causes crash
|
||||
@override
|
||||
void dispose() {
|
||||
_playPauseFocusNode.dispose(); // First
|
||||
// ... more disposals ...
|
||||
_playPauseFocusNode.dispose(); // SECOND - CRASH!
|
||||
super.dispose();
|
||||
}
|
||||
```
|
||||
|
||||
**Fix:** Single disposal pass
|
||||
```dart
|
||||
// GOOD - Each node disposed once
|
||||
@override
|
||||
void dispose() {
|
||||
_playPauseFocusNode.dispose();
|
||||
_prevFocusNode.dispose();
|
||||
_nextFocusNode.dispose();
|
||||
_sliderFocusNode.dispose();
|
||||
_backFocusNode.dispose();
|
||||
_audioFocusNode.dispose();
|
||||
super.dispose(); // No duplicate disposals
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📊 MEDIUM-IMPACT FIXES (Hour 4-6)
|
||||
|
||||
### P2-1: Consolidate DNS Resolution
|
||||
**Impact:** Unified DNS strategy, -50% duplicate resolution
|
||||
**Files:** `dns_resolver.dart` + `dns_interceptor.dart`
|
||||
|
||||
**Current:** Two separate implementations, separate caches
|
||||
```dart
|
||||
// BAD - Duplicate implementations, no cache sharing
|
||||
class DnsResolver { static final _cache = {}; }
|
||||
class DnsFallbackInterceptor { final _dnsCache = {}; }
|
||||
```
|
||||
|
||||
**Fix:** Single unified DNS service
|
||||
```dart
|
||||
// GOOD - Single cache, shared across app
|
||||
class UnifiedDnsResolver {
|
||||
static final _cache = <String, (String, DateTime)>{};
|
||||
|
||||
static String? getCached(String host) {
|
||||
final (ip, expires) = _cache[host] ?? (null, DateTime(2000));
|
||||
return DateTime.now().isBefore(expires) ? ip : null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### P2-2: Variable Buffer Size for VOD (Device-Aware)
|
||||
**Impact:** Prevent OOM on low-end devices
|
||||
**File:** `lib/features/iptv/screens/native_player_screen.dart:187`
|
||||
|
||||
**Current:** Fixed 100MB
|
||||
```dart
|
||||
// BAD - 100MB on all devices, 1GB RAM devices crash
|
||||
_player.setProperty('demuxer-max-bytes', '100000000');
|
||||
```
|
||||
|
||||
**Fix:** Device-aware sizing
|
||||
```dart
|
||||
// GOOD - 20MB low-end, 100MB high-end
|
||||
final maxBytes = device.ram < 2 ? 20000000 : 100000000;
|
||||
_player.setProperty('demuxer-max-bytes', maxBytes.toString());
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### P2-3: Fix Movies Tab Infinite Retry Loop
|
||||
**Impact:** Prevent UI freeze on API failures
|
||||
**File:** `lib/features/iptv/widgets/mobile_movies_tab.dart:225`
|
||||
|
||||
**Current:** Retry scheduled on every build
|
||||
```dart
|
||||
// BAD - Infinite loop if API fails
|
||||
if (_categories.isEmpty && !_isLoading) {
|
||||
WidgetsBinding.instance.addPostFrameCallback((_) {
|
||||
if (mounted && _categories.isEmpty) {
|
||||
_loadCategories(); // Retry forever
|
||||
}
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Fix:** Count retries, add exponential backoff
|
||||
```dart
|
||||
// GOOD - Max 3 retries with 2s+ delay
|
||||
if (_categories.isEmpty && !_isLoading && _retryCount < 3) {
|
||||
await Future.delayed(Duration(seconds: 2 << _retryCount));
|
||||
_loadCategories();
|
||||
_retryCount++;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### P2-4: Pause HeroCarousel Auto-Play When Off-Screen
|
||||
**Impact:** -1 rebuild/sec when carousel invisible
|
||||
**File:** `lib/core/widgets/components/hero_carousel.dart:42`
|
||||
|
||||
**Current:** Always runs
|
||||
```dart
|
||||
// BAD - Runs even when user is on another tab
|
||||
_pageController?.nextPage(
|
||||
duration: Duration(seconds: 8),
|
||||
curve: Curves.easeInOut,
|
||||
);
|
||||
```
|
||||
|
||||
**Fix:** Pause when visibility changes
|
||||
```dart
|
||||
// GOOD - Only animate when visible
|
||||
if (_isVisible) {
|
||||
_pageController?.nextPage(duration, curve);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🧹 CLEANUP FIXES (Hour 6-7)
|
||||
|
||||
### P3-1: Disable LogInterceptor in Production
|
||||
**Impact:** -5% CPU during large downloads
|
||||
**File:** `lib/core/api/api_client.dart:21`
|
||||
|
||||
```dart
|
||||
// BAD - Logs full request/response on every call
|
||||
_dio.interceptors.add(LogInterceptor(
|
||||
requestBody: true,
|
||||
responseBody: true,
|
||||
));
|
||||
|
||||
// GOOD - Disabled in production
|
||||
if (kDebugMode) {
|
||||
_dio.interceptors.add(LogInterceptor(...));
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### P3-2: Remove Unused go_router Dependency
|
||||
**Impact:** -2% bundle size
|
||||
**File:** `pubspec.yaml:28`
|
||||
|
||||
```yaml
|
||||
# REMOVE this line entirely
|
||||
go_router: ^13.2.5
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### P3-3: Cancel Clock Stream Properly
|
||||
**Impact:** -1 rebuild/sec
|
||||
**File:** `lib/mobile/widgets/mobile_scaffold.dart:30`
|
||||
|
||||
```dart
|
||||
// BAD - Never cancelled, runs forever
|
||||
_clockStream = Stream.periodic(Duration(seconds: 1));
|
||||
|
||||
// GOOD - Cancel on dispose
|
||||
@override
|
||||
void dispose() {
|
||||
_clockSubscription?.cancel();
|
||||
super.dispose();
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### P3-4: Declare Color Constants
|
||||
**Impact:** Minor GC pressure reduction
|
||||
**Files:** Multiple files
|
||||
|
||||
```dart
|
||||
// BAD - New Color object on every build
|
||||
Color shade = Colors.blue.withOpacity(0.8);
|
||||
|
||||
// GOOD - Declare once
|
||||
static const Color BUTTON_SHADE = Color.fromARGB(204, 33, 150, 243);
|
||||
```
|
||||
|
||||
