+
+## Metrics Collected
+
+- **Sandbox Creation Time:** Time to create a new sandbox
+- **Command Execution Time:** Time to execute individual commands
+- **Success Rate:** Percentage of successful operations
+- **File Operations:** Upload/download performance
+- **Snapshot Lifecycle:** Git clone, snapshot creation, and restoration
+
+## Test Scenarios
+
+1. **Basic Commands:** Shell commands (echo, pwd, ls, whoami, date)
+2. **Python Execution:** Python script execution and version checks
+3. **File Operations:** File upload/download with various sizes
+4. **Computational Tasks:** CPU-intensive Python operations
+5. **Snapshot Lifecycle:** Git clone, file creation, snapshot, kill, and restore
+
+## Automation
+
+This summary is automatically updated when new benchmark results are available.
+Results are committed to the repository for historical tracking.
