# SystemResourceLimits
<a name="API_SystemResourceLimits"></a>

Contains information about system resource limits that the AWS IoT Greengrass Core software applies to a component's processes. For more information, see [Configure system resource limits for components](https://docs.aws.amazon.com/greengrass/v2/developerguide/configure-greengrass-core-v2.html#configure-component-system-resource-limits).

 ** cpus **   <a name="greengrassv2-Type-SystemResourceLimits-cpus"></a>
The maximum amount of CPU time that a component's processes can use on the core device. A core device's total CPU time is equivalent to the device's number of CPU cores. For example, on a core device with 4 CPU cores, you can set this value to `2` to limit the component's processes to 50 percent usage of each CPU core. On a device with 1 CPU core, you can set this value to `0.25` to limit the component's processes to 25 percent usage of the CPU. If you set this value to a number greater than the number of CPU cores, the AWS IoT Greengrass Core software doesn't limit the component's CPU usage.

 ** memory **   <a name="greengrassv2-Type-SystemResourceLimits-memory"></a>
The maximum amount of RAM, expressed in kilobytes, that a component's processes can use on the core device.
