One day prior to project completion, I came up with another, more optimal algorithm and completely rewrote the code for the function and the result was several times faster and spend less server resources.

Once, until the project completion, i unwillingly plunged into another, much optimal algorithm and fully artist enamored function code and the result was several times faster and spend less server resources.
