+# Quick Answer: Proxmox Compatibility
+
+## ⚠️ TL;DR: **NO, not on Proxmox host. YES, inside VMs.**
+
+---
+
+## 🔴 Running on Proxmox Host: **NOT RECOMMENDED**
+
+### Why Not?
+
+1. **zram** will steal RAM from your VMs (up to 50% of total RAM)
+2. **tmpfs** will allocate 40% of RAM, reducing VM memory
+3. **Kernel parameters** are tuned for desktop, not hypervisor workloads
+4. May cause **VM performance degradation** and instability
+
+### What Could Go Wrong?
+
+- VMs running slower due to memory pressure
+- Increased swap usage on VMs
+- Proxmox host becomes less responsive
+- Unpredictable behavior under heavy VM load
+
+---
+
+## ✅ Running Inside VMs: **FULLY SAFE & RECOMMENDED**
+
+Perfect use case! Run the optimizer **inside your desktop VMs**:
+
+```bash
+# Inside your Ubuntu/Fedora/etc desktop VM:
+sudo ./one-button-optimizer.sh
+```
+
+### Benefits Inside VMs:
+- ✅ Full optimizations without affecting host
+- ✅ Browser/IDE caching works great
+- ✅ Each VM gets its own optimized environment
+- ✅ No risk to other VMs or Proxmox host
+
+---
+
+## 📊 Safe to Use Anywhere (Read-Only Tools)
+
+These monitoring scripts are **100% safe** on Proxmox host or VMs:
+
+```bash
+./quick-status-check.sh     # System overview
+./tmpfs-info.sh              # tmpfs information  
+./benchmark-tmpfs.sh         # Performance test
+./benchmark-realistic.sh     # Cache simulation
+```
+
+They only **read** information, make no changes.
+
+---
+
+## 🛡️ Protection Built-In
+
+The script now **detects Proxmox** and shows this warning:
+
+```
+⚠️  Proxmox VE host detected!
+
+This tool is designed for desktop Linux systems and may not be
+suitable for Proxmox hosts. Key concerns:
+
+  🔴 zram: Reduces RAM available for VMs
+  🟡 tmpfs: Allocates significant memory (up to 40%)
+  🟡 Kernel params: Tuned for desktop, not hypervisor
+
+Continue anyway? (y/N):
+```
+
+You can abort safely or proceed if you understand the risks.
+

+
+## 🎯 Recommendations by Use Case
+
+| Scenario | Recommendation | Reason |
+|----------|---------------|--------|
+| Desktop VM | ✅ **USE IT** | Perfect match, fully safe |
+| Proxmox Host | ❌ **DON'T USE** | Wrong optimizations |
+| Container (LXC) | ⚠️ **MAYBE** | Depends on privileged/unprivileged |
+| Testing | 📊 **READ-ONLY TOOLS** | Safe monitoring only |
+
+---
+
+## 💡 Summary
+
+**Simple Rule:**
+- Inside VMs: **GO FOR IT!** 🚀
+- On Proxmox host: **DON'T!** ⛔
+- Monitoring scripts: **Always safe** 👍
