What are the thread limitations imposed by Dispatchers.Default in coroutines?

Dispatchers.Default in Kotlin Coroutines uses a thread pool whose size by default is equal to the number of available processor cores (Runtime.getRuntime().availableProcessors()). This means that the number of concurrently running threads is limited to the number of CPU cores, which helps efficiently utilize resources and avoid excessive context switching.

If needed, the pool size can be changed by creating a custom CoroutineDispatcher with the desired number of threads, but the standard Dispatchers.Default is optimized for most computational tasks.
