# CPU cores limit

## Overview

Compresto allows you to limit the number of CPU cores used during compression. This setting helps balance compression performance with system responsiveness.

## Available Options

| Option      | Description                                                |
| ----------- | ---------------------------------------------------------- |
| **2 cores** | Minimal CPU usage, keeps system highly responsive          |
| **4 cores** | Balanced CPU usage                                         |
| **Max**     | Uses all available cores for fastest compression (default) |

## When to Use

Limiting CPU cores can improve system performance during compression by:

* Keeping your Mac responsive while compressing large files
* Allowing you to continue working on other tasks during compression
* Reducing system heat and fan noise on intensive compression jobs

## How to Configure

<Steps>
  <Step>
    Open Compresto
  </Step>

  <Step>
    Go to **Settings** > **Advanced**
  </Step>

  <Step>
    Adjust the **CPU cores for compression** slider

<Note>
  Using fewer cores will result in slower compression times, but your system will remain more responsive for other tasks.
