For appliances that include Napatech capture cards, BIOS settings must be tuned to avoid latency and timing issues during high-throughput packet capture. Please ensure the following:
BIOS Setting | Recommended Value | Notes |
|---|---|---|
CPU Virtualization (VT-x / SVM) | Disabled | Maintains timestamp variability |
C-States (CPU sleep states) | Disabled | Ensures consistent CPU performance |
Power Profile | Performance mode | Avoid “Balanced” or “Power Saving” profiles |
Server BIOS recommended values - for custom deployments
On systems without Napatech cards (e.g. VMX-Analysis-only appliances), power-saving profiles may be acceptable if energy efficiency is a concern.
