The invention discloses a starting speed optimization method and device for a vehicle-mounted system and an application, equipment and a medium, and the method comprises the steps: in a system starting stage, triggering a pre-reading service according to system events of different sub-stages, loading resource files corresponding to the different sub-stages to a cache in an asynchronous loading manner, and in an application starting stage, loading resource files corresponding to the different sub-stages to the cache in an asynchronous loading manner. And in response to a click operation of a user on the target application icon, asynchronously triggering the pre-reading service to load the installation package resource of the target application while the host process of the target application is started. In the system starting stage, the resources are pre-loaded into a cache of a memory by triggering a pre-reading service in a segmented manner, so that jamming caused by synchronous IO waiting when follow-up processes need the resources is avoided, and IO bandwidth saturation caused by traditional'one-time pre-loading 'is avoided through segmented pre-loading. When the user clicks the application icon, the pre-reading service is triggered asynchronously, the application related resources are pre-loaded, and the situation that an application starting main thread is blocked in the pre-loading process is avoided.
