Can some help what will be the difference in both approach
```Dispatchers.IO.limitedParallelism(64)

OR

System.setProperty(IO_PARALLELISM_PROPERTY_NAME, 50.toString()) ```
Is it just 1st one will limit for anyone using the dispatcher instance created
and 2nd one will always set the limit of each time we create a dispatcher instance

Can someone share more insights on this

With <https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/-coroutine-dispatcher/limited-parallelism.html|limitedParallelism>, you can create a view of a dispatcher, that limits the number of coroutines running in parallel to the given number. So, e.g. `Dispatchers.IO.limitedParallelism(4)` returns a  dispatcher that uses the IO dispatcher, but runs at most 4 coroutines at the same time. Of course the number of parallelism could never be higher than the number of threads in the original Dispatcher (e.g. a single-threaded dispatcher with a parallelism of 4 makes no sense). Note that calling this function does not change the original dispatcher (IO in this case).

The <https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/-i-o_-p-a-r-a-l-l-e-l-i-s-m_-p-r-o-p-e-r-t-y_-n-a-m-e.html|IO_PARALLELISM_PROPERTY_NAME> sets the system-wide maximum number of threads used by `<http://Dispatchers.IO|Dispatchers.IO>`, so that applies to the IO dispatcher itself. Note that this is a JVM property only, if I am not mistaken.
