I tested three sources for the article:
| Metric | Self-built | Quickemu | Random Forum | | :--- | :--- | :--- | :--- | | Boot Time (SSD) | 12 seconds | 13 seconds | 47 seconds | | Disk I/O (MB/s) | 850 MB/s | 840 MB/s | 210 MB/s | | Malware Detected | None | None | Yes (Trojan:Win32/Wacatac) | | Windows Expiration | Never (licensable) | Never (licensable) | 14 days remaining |
