v1.1.0: Performance scaling with RSS URL parameters

- Add support for ?limit= URL parameters (up to 100 posts/feed)
- Update documentation with performance scaling guidelines
- Add progressive scaling examples in rss_feeds.example.txt
- Include optimization strategies and troubleshooting
- Maintain backward compatibility with standard RSS feeds

+# Performance Scaling & Configuration
+
+## 🚀 RSS Feed Optimization (v1.1.0+)
+
+GTS-HolMirDas supports URL parameters to dramatically increase content discovery without additional API calls.
+
+### RSS Feed Limits
+
+Most Mastodon-compatible instances support the `?limit=X` parameter:
+
+```
+# Default behavior (20 posts per feed)
+https://mastodon.social/tags/homelab.rss
+
+# Increased limits (up to 100 posts per feed)
+https://mastodon.social/tags/homelab.rss?limit=50
+https://fosstodon.org/tags/docker.rss?limit=100
+```
+
+**Supported limits:** 20 (default), 50, 75, 100 (instance-dependent)
+
+### Performance Impact
+
+| Configuration | Posts/Run | API Calls | Processing Time |
+|---------------|-----------|-----------|-----------------|
+| Standard (limit=20) | ~100 posts | 30+ feeds | 2-5 minutes |
+| Optimized (limit=50) | ~300 posts | 30+ feeds | 5-10 minutes |
+| Maximum (limit=100) | ~600 posts | 30+ feeds | 8-15 minutes |
+
+## ⚙️ Configuration Tuning
+
+### Environment Variables
+
+```env
+# Processing Configuration
+MAX_POSTS_PER_RUN=75          # Increase for higher limits
+DELAY_BETWEEN_REQUESTS=1      # Balance speed vs. server load
+RSS_URLS_FILE=/app/rss_feeds.txt
+
+# Recommended combinations:
+# Conservative: MAX_POSTS_PER_RUN=40, limit=50
+# Balanced:     MAX_POSTS_PER_RUN=75, limit=100  
+# Aggressive:   MAX_POSTS_PER_RUN=100, limit=100
+```
+
+### RSS Feed Strategy
+
+```
+# Progressive scaling approach:
+# 1. Start with mixed limits to test performance
+# 2. Increase gradually based on server capacity
+# 3. Monitor GoToSocial memory usage
+
+# Example progression:
+https://mastodon.social/tags/homelab.rss?limit=50
+https://fosstodon.org/tags/selfhosting.rss?limit=75
+https://chaos.social/tags/docker.rss?limit=100
+```
+
+## 📊 Monitoring & Optimization
+
+### Performance Metrics
+
+The statistics output shows real-time performance:
+
+```
+📊 GTS-HolMirDas Run Statistics:
+   ⏱️  Runtime: 0:08:42
+   📄 Total posts processed: 487
+   🌐 Current known instances: 3150
+   ➕ New instances discovered: +45
+   📡 RSS feeds processed: 102
+   ⚡ Posts per minute: 56.0
+```
+
+### Optimization Guidelines
+
+**Memory Usage:**
+- Monitor GoToSocial memory consumption during runs
+- Each 100 additional posts ≈ ~2-5MB additional RAM
+- Recommended: 1GB+ RAM for aggressive configurations
+
+**Processing Time:**
+- Scales linearly with `MAX_POSTS_PER_RUN × number_of_feeds`
+- Duplicate detection becomes more important at scale
+- Consider running frequency vs. content volume
+
+**Federation Growth:**
+- Higher limits = more diverse instance discovery
+- Expect 20-50+ new instances per optimized run
+- Balance discovery rate with storage capacity
+
+### Troubleshooting High-Volume Setups
+
+**If processing takes too long:**
+```env
+MAX_POSTS_PER_RUN=50          # Reduce from 75/100
+DELAY_BETWEEN_REQUESTS=2      # Increase from 1
+```
+
+**If GoToSocial uses too much memory:**
+- Reduce RSS feed count temporarily
+- Lower `?limit=` parameters to 50 instead of 100
+- Increase run frequency instead of volume
+
+**If duplicate detection is slow:**
+- Storage cleanup: `docker-compose exec gts-holmirdas rm -f /app/data/processed_urls.json`
+- This forces fresh state tracking (posts will be reprocessed once)
+
+## 🎯 Best Practices
+
+### Scaling Strategy
+
+1. **Start Conservative:** `limit=50`, `MAX_POSTS_PER_RUN=40`
+2. **Monitor Performance:** Check RAM usage and processing time
+3. **Scale Gradually:** Increase to `limit=75`, then `limit=100`
+4. **Optimize Mix:** Use different limits per instance based on quality
+
+### Instance Selection
+
+**High-quality instances for aggressive limits:**
+```
+# Tech-focused instances (good signal-to-noise ratio)
+https://fosstodon.org/tags/homelab.rss?limit=100
+https://infosec.exchange/tags/security.rss?limit=100
+
+# General instances (moderate limits recommended)  
+https://mastodon.social/tags/technology.rss?limit=50
+```
+
+**Performance tip:** Specialized instances often have higher content quality at scale than general-purpose instances.
