are there any major difference between

<http://Dispatchers.IO|Dispatchers.IO>

and

Dispatchers.DEFAULT

that one needs to know about

<http://Dispatchers.IO|Dispatchers.IO>

should be used for blocking operations and

Dispatchers.DEFAULT

should be used for non-blocking.

Yes.

Default

is for CPU-intensive tasks and is limited by the # of CPU cores, while

IO

is for blocking operations that are not supposed to consume CPU (by default it is configured to support 64 concurrent operations)
