+### Specifying the Max Execution Time
+
+By default, Laravel Octane sets a maximum execution time of 30 seconds for incoming requests via the `max_execution_time` option in your application's `config/octane.php` configuration file:
+
+```php
+'max_execution_time' => 30,
+```
+
+This setting defines the maximum number of seconds that an incoming request is allowed to execute before being terminated. Setting this value to `0` will disable the execution time limit entirely. This configuration option is particularly useful for applications that handle long-running requests, such as file uploads, data processing, or API calls to external services.
+
+> [!WARNING]
+> When you modify the `max_execution_time` configuration, you must restart the Octane server for the changes to take effect.
