actually Future.sequence() will run dispatched. it would just make no sense to run the single number concurrently, as the go version won&#x27;t do this, too.
Future.sequence uses the global Executer.<p><pre><code>        sum := 0
        for i := 0; i &lt; div; i++ {
            sub_num := num + i * (size &#x2F; div)
            go skynet(rc, sub_num, size &#x2F; div, div)
        }
</code></pre>
This is the go version and only the inside will run on a thread so I made a fair comparsion P.S: The go version will actually run single threaded when you are having GOMAXPROCS=1.
