It lacks many of the aggressive timer issues found in later 15.7 or 15.8 versions.

| Area | Limitation | | :--- | :--- | | | Sub-1 Gbps routing (often 200-400 Mbps on modern hardware). | | Timer precision | Sub-second routing timers (e.g., BFD) are inaccurate. | | Interrupts | No hardware interrupt coalescing; high CPU on packet bursts. | | Layer 2 | No switching (no PVST, no EtherChannel). Use a separate L2 image. | | K9 crypto | IPsec throughput is CPU-bound (~50-80 Mbps). |
