Most efficient way to split a vector into several
Aug 27, 2014 · In otherwords, you are allocating a new vector twice in your loop, and copying each element twice. By prealloating a vector above the loop you are only allocating one vector (the one that doSend recieves). To avoid copying elements twice is harder. Since you can invalidate the vector's elements, swapping and then copying is possible.
