## CPU consumption {#dex-sys-requirements__section_v45_2xx_ckc}

Digital End-User Experience (DEX) uses approximately 1% average CPU for both Windows and macOS devices.

## CPU protection threshold {#dex-sys-requirements__section_z3w_5xx_ckc}

When an agent meets the configured thresholds specified in the agent's acc.yml file, it enters CPU protection mode, either for an individual check or for all checks. For more information about the
CPU protection threshold, see [Agent Client Collector CPU protection thresholds](https://www.servicenow.com/docs/v~aWwmKuZB26lyEv7Iy4FA "When an agent meets the configured thresholds specified in the agent's acc.yml file, it enters CPU protection mode, either for an individual check or for all checks. Agents in CPU protection mode appear in the agent logs with the syntax Agent Protection.")  
Note:  
Configure the ACC CPU Protection Threshold to 20% for DEX deployments.
