Rxjava: About Schedulers.computation()

[lolobug]

"meant for computational work such as event-loops and callback processing; do not use this scheduler for I/O (use Schedulers.io( ) instead); the number of threads, by default, is equal to the number of processors"

I wonders why.
What's the advantage of running in a thread picked from a fixed number thread pool when doing computational work.
