Kui palju niite luuakse vaikimisi Kotlin korutinates Dispatchers.Default poolt?

By default, Dispatchers.Default in Kotlin Coroutines creates a thread pool whose size is equal to the number of available processor cores, but not less than 2.

This means that if the device has 4 cores, the pool will consist of 4 threads; if it has 1 core, at least 2 threads.

This is done to optimize CPU resource utilization when executing parallel tasks, avoiding creating an excessive number of threads that could reduce performance due to context switching.

Example:

println(Runtime.getRuntime().availableProcessors()) // number of cores
println(Dispatchers.Default.toString())

Thus, Dispatchers.Default adapts to the hardware capabilities of the device.
