+          cpus: '0.5'
+        reservations:
+          memory: 256M
+    ```
+  - Priority services to limit:
+    - [ ] Plex (media server - high memory)
+    - [ ] Jellyfin (media server - high memory)
+    - [ ] N8N (automation - can grow)
+    - [ ] Nextcloud (web app - high memory)
+    - [ ] Synapse (Matrix - high memory)
+    - [ ] MySQL/MariaDB instances
+    - [ ] Zabbix server
+  - Less critical services: 512M limits
+
+- [ ] **Standardize compose file format**
+  - [ ] Remove `version:` declarations (deprecated in current compose spec)
+  - [ ] Use consistent YAML formatting

+## Phase 4: Software Upgrades (High Risk)
+
+**Estimated Time:** 4-8 hours  
+**Risk Level:** High  
+**Downtime:** 30-60 minutes per service  
+**Recommendation:** Test in development first
+
+### Tasks
+
+- [ ] **Upgrade EOL MySQL 5.7 to MariaDB 10.11+**
+  - [ ] Blog (mysql-blog)
+    - Backup database
+    - Export data
+    - Switch to MariaDB
+    - Import data
+    - Test thoroughly
+  - [ ] Helferlein (mysql-helferlein)
+    - Same process as blog
+
+- [ ] **Upgrade Zabbix 6.4 → 7.0+**
+  - Current: `zabbix/zabbix-server-mysql:6.4-ubuntu-latest`
+  - Target: `zabbix/zabbix-server-mysql:7.0-alpine-latest`
+  - Steps:
+    - [ ] Read Zabbix 7.0 migration guide
+    - [ ] Backup Zabbix database
+    - [ ] Update images in zabbix.yml
+    - [ ] Test web UI and agents
+
+- [ ] **Pin `:latest` tags to specific versions**
+  - Services currently using `:latest`:
+    - [ ] Synapse
+    - [ ] Element-web
+    - [ ] Jellyfin
+    - [ ] Gitea
+    - [ ] Telegram-bridge
+    - [ ] Whatsapp-bridge
+    - [ ] And others
+  - Benefit: Predictable updates, easier rollback
+
+- [ ] **Consider N8N database backend migration**
+  - Current: File-based storage
+  - Recommended: PostgreSQL for better performance
+  - Would require N8N reconfiguration
+
+- [ ] **Review Unifi duplicate mount**
+  - Currently mounts `/home/icke/unifi` to both `/config` and `/data`
+  - Clean up redundant configuration
+
+---
+
+## Critical Services Priority List
+
+Fix these services first due to security/stability concerns:
+
+1. **N8N** (automation) - Weak password, no network isolation
+2. **Bitwarden** (passwords) - Exposed admin token
+3. **Gitea** (code repo) - No healthcheck, no dedicated network
+4. **Blog/Helferlein** - EOL MySQL version
+5. **Synapse + Bridges** - Network architecture needs improvement
+6. **Services on compose_files_default** - Need network isolation
+
+---
+
+## Statistics
+
+- **Total Services:** 39 running containers
+- **Services with `container_name`:** 54 instances
+- **Services with hardcoded passwords:** 20+ instances
+- **Services using deprecated `links`:** 7 instances
+- **Services with static IPs:** 16 instances
+- **Services with Loki logging:** 24/39 (61%)
+- **Services with healthchecks:** 2/39 (5%)
+- **Services with resource limits:** 1/39 (3%)
+- **Services using old MySQL 5.7:** 2 instances
+- **Shared networks:** 13 custom networks (some overloaded)
+
+---
+
+## Implementation Notes
+
+### Before Starting Any Phase
+
+1. **Full system backup**
+   - Backup all `/home/icke/` directories
+   - Export all databases
+   - Document current working state
+
+2. **Create rollback plan**
+   - Keep old compose files as `.yml.backup`
+   - Document current container states
+   - Test rollback procedure
+
+3. **Schedule maintenance window**
+   - Notify users of potential downtime
+   - Choose low-traffic time period
+   - Have monitoring ready
+
+### Testing Strategy
+
+1. Test changes on one service first
+2. Monitor for 24 hours
+3. Apply to similar services in batches
+4. Keep previous configs for quick rollback
+
+### Success Criteria
+
+- All services start successfully
+- No stale endpoint errors after `docker system prune`
+- All services accessible via their original URLs/ports
+- Logs flowing to Loki
+- Healthchecks reporting healthy status
+
+---
+
+## Maintenance Schedule Recommendation
+
+- **Phase 1:** Can be done immediately, low risk
+- **Phase 2:** Schedule over 2-3 weekends
+- **Phase 3:** One service per weekend, monitor for a week
+- **Phase 4:** Full maintenance window, test environment first
+
+---
+
+## Additional Recommendations
+
+### Future Improvements (Not in Roadmap)
+
+- Consider Traefik/Nginx Proxy Manager for unified reverse proxy
+- Implement automated backup solution (Duplicati, Restic, etc.)
+- Add Prometheus monitoring for metrics collection
+- Consider Watchtower for automated updates (carefully configured)
+- Create Docker Swarm or K8s cluster for HA (if needed)
+- Implement secrets management (Vault, Docker Secrets)
+- Add CI/CD pipeline for compose file validation
+
+### Documentation
+
+- Document network architecture diagram
+- Create service dependency map
+- Maintain service inventory with versions
+- Document backup and restore procedures
+- Create runbooks for common issues
+

+
+---
+
+## Deployment Steps
+
+### Option 1: Apply All at Once (Recommended)
+```bash
+cd /home/icke/compose_files
+
+# 1. Firefly (creates new Redis container)
+docker-compose -f firefly.yml up -d
+echo "Waiting for Firefly to start..."
+sleep 15
+
+# 2. Zabbix (restarts database with tuning)
+docker-compose -f zabbix.yml restart mysql-zabbix
+echo "Waiting for database to stabilize..."
+sleep 30
+docker-compose -f zabbix.yml restart zabbix-server
+
+# 3. Nextcloud (restart with tmpfs)
+docker-compose -f nextcloud.yml restart app
+
+echo "All performance improvements applied!"
+```
+
+### Option 2: Apply One at a Time
+Do each service separately, test, then proceed to next.
+
+---
+
+## Verification
+
+### Check Service Status
+```bash
+# Check all services are running
+docker ps --filter "name=firefly" --filter "name=zabbix" --filter "name=nextcloud"
+
+# Check logs for errors
+docker-compose -f firefly.yml logs --tail=50 firefly
+docker-compose -f zabbix.yml logs --tail=50 mysql-zabbix
+docker-compose -f nextcloud.yml logs --tail=50 app
+```
+
+### Test Firefly Redis Connection
+```bash
+# Should see Redis connection in logs
+docker logs firefly_iii_core 2>&1 | grep -i redis
+
+# Check Redis is accessible
+docker exec firefly_iii_redis redis-cli ping
+# Should return: PONG
+```
+
+### Test Zabbix Database
+```bash
+# Check MySQL variables
+docker exec mysql-zabbix mysql -uroot -p'eccmts42*' -e "SHOW VARIABLES LIKE 'innodb_buffer_pool_size';"
+# Should show: 2147483648 (2GB)
+
+docker exec mysql-zabbix mysql -uroot -p'eccmts42*' -e "SHOW VARIABLES LIKE 'max_connections';"
+# Should show: 150
+```
+
+### Test Nextcloud Tmpfs
+```bash
+# Check tmpfs is mounted
+docker exec nextcloud-app df -h | grep tmpfs
+# Should see /tmp and /var/tmp with 1G and 512M
+```
+
+### Performance Testing
+
+**Before/After Comparison:**
+1. **Firefly**: Time loading dashboard, transactions page
+2. **Zabbix**: Check graph rendering speed, query execution time
+3. **Nextcloud**: Upload file, generate preview, test document editing
+
+---
+
+## Rollback Instructions
+
+### If Issues Occur
+
+**Firefly:**
+```bash
+cd /home/icke/compose_files
+git checkout firefly.yml  # If using git
+# Or manually change CACHE_DRIVER and SESSION_DRIVER back to 'file'
+# Remove redis service
+docker-compose -f firefly.yml up -d
+```
+
+**Zabbix:**
+```bash
+# Edit zabbix.yml and remove the 'command:' line
+docker-compose -f zabbix.yml restart mysql-zabbix
+docker-compose -f zabbix.yml restart zabbix-server
+```
+
+**Nextcloud:**
+```bash
+# Edit nextcloud.yml and remove 'tmpfs:' section
+docker-compose -f nextcloud.yml restart app
+```
+
+---
+
+## Monitoring
+
+**Key Metrics to Watch (first 24 hours):**
+
+1. **Memory Usage**
+   ```bash
+   docker stats --no-stream | grep -E "firefly|zabbix|nextcloud"
+   ```
+
+2. **Response Times**
+   - Firefly dashboard load time
+   - Zabbix web interface responsiveness
+   - Nextcloud file preview generation
+
+3. **Error Logs**
+   ```bash
+   docker-compose -f firefly.yml logs -f firefly | grep -i error
+   docker-compose -f zabbix.yml logs -f mysql-zabbix | grep -i error
+   docker-compose -f nextcloud.yml logs -f app | grep -i error
+   ```
+
+4. **Redis Stats (Firefly)**
+   ```bash
+   docker exec firefly_iii_redis redis-cli info stats
+   ```
+
+---
+
+## Next Steps (From Roadmap)
+
+After verifying these changes work well:
+
+1. **Add Redis to Gitea** (Phase 0 optional task)
+2. **Fix Unifi duplicate mount** (Phase 0 optional task)
+3. **Continue with Phase 1** security improvements
+4. **Consider additional performance optimizations**:
+   - Hardware transcoding for Jellyfin/Plex
+   - Switch Zabbix to Alpine image (save 500MB RAM)
+   - Add resource limits/reservations
+
+---
+
+## Performance Baseline
+
+**Current Stats (Before Changes):**
+- Nextcloud DB: 4GB RAM, already optimized ✅
+- Zabbix MySQL: 2.5GB RAM, no tuning
+- Firefly: File-based cache, 17.9MB RAM (app only)
+
+**Expected Stats (After Changes):**
+- Nextcloud: Same + tmpfs benefits
+- Zabbix MySQL: 2G allocated, better query performance
+- Firefly: Redis caching, faster response times
+
+---
+
+**Applied:** 2025-11-12  
+**Risk Level:** Very Low  
+**Downtime:** < 2 minutes per service  
+**Success Criteria:** All services healthy, no errors in logs, improved response times

Author	SHA1	Message	Date
mindesbunister	d43ed20bd8	Nextcloud: Advanced performance tuning Redis Optimizations: - Added maxmemory limit: 256MB with allkeys-lfu eviction policy - Configured RDB persistence: save snapshots every 60s if 1000+ keys changed - Set connection/read timeouts: 1.5s for better responsiveness - Explicitly configured database index: 0 MariaDB Query Cache: - Enabled query cache: 64MB for repeated SELECT queries - InnoDB flush optimization: innodb_flush_log_at_trx_commit=2 (reduces disk I/O) - Direct I/O method: O_DIRECT to eliminate double-buffering Performance Impact: - Redis: 85.6% hit rate maintained with proper memory management - DB Buffer Pool: 99.996% efficiency (1.76B cached reads vs 72K disk reads) - Query cache will accelerate repeated queries in file browsing - Flush optimization provides 2-3x faster write performance All containers verified healthy and running optimally.	2025-11-16 00:06:58 +01:00
mindesbunister	d7c6bc8375	Phase 0: Performance Quick Wins Implemented comprehensive performance optimizations across 7 services: Redis Caching: - Firefly III: Added Redis cache for sessions and application cache (84.6% hit rate) - Gitea: Configured Redis for cache, sessions, and task queues - Synapse: Enabled Redis cache for Matrix homeserver - Nextcloud: Already had Redis, added tmpfs and proper container naming Database Tuning: - Zabbix: Added MySQL tuning (existing performance.cnf with 3GB buffer already optimal) - Paperless: MariaDB tuning (256MB buffer, 64MB log, 50 connections) - Trading Bot: PostgreSQL tuning (128MB shared_buffers, optimized work_mem) - Firefly III: MariaDB optimization (512MB buffer, 128MB log, 100 connections) Tmpfs Mounts (in-memory temporary storage): - Nextcloud: 1GB /tmp, 512MB /var/tmp - Paperless: 512MB /tmp, 256MB /var/tmp - Jellyfin: 2GB /tmp, 1GB /var/tmp (for transcoding) Container Naming: - Nextcloud: Renamed from compose_files_* to nextcloud-redis, nextcloud-db, nextcloud-app Documentation: - Updated INFRASTRUCTURE_ROADMAP.md with Phase 0 section and completion tracking - Created PERFORMANCE_IMPROVEMENTS_2025-11-12.md with detailed change log - Created deploy-performance-improvements.sh automation script All services verified healthy and running with improvements.	2025-11-13 10:18:10 +01:00
