If your instance runs out of [CPU burst capacity](https://docs.aws.amazon.com/en_us/lightsail/latest/userguide/amazon-lightsail-viewing-instance-burst-capacity.html), then the CPU's steal time increases. To reduce the steal time, identify services that use too many resources, and then deactivate them. If you still experience a high steal time, then create a larger instance.

Resolution
----------

### Uninstall or deactivate nonessential resources

Complete the following steps:

1. Identify the services that use your CPU resources.  
    **Note:** To view system performance, run the **top** command in Linux, or use Task Manager in Windows.
2. Uninstall or deactivate nonessential services.

### Create a larger instance

Complete the following steps:

1. [Create a Lightsail block storage disk snapshot](https://docs.aws.amazon.com/en_us/lightsail/latest/userguide/create-block-storage-disk-snapshot.html) of your instance.
2. Use the snapshot to [create a larger instance](https://docs.aws.amazon.com/en_us/lightsail/latest/userguide/how-to-create-larger-instance-from-snapshot-using-console.html#create-larger-resource-from-snapshot).
