Hey!
I'd say the function is too small (plus is allocating and deallocating the vector each time is called). In cases like this one, it may be counter productive to use the thread. This is because the overhead that the thread pool adds (to keep track of the queue, callbacks, etc) is too big in comparison with the time required to execute the function, which is really really small.
If you want to execute the same light function multiple times, you can probably build a less generic thread pool that is optimized for that. Nevertheless, for such simple math operations, the overhead may still be too high.

Hope this helps!
