What WARP does is prioritize execution of the current script over other jobs Snap! usually keeps your system busy with, mostly checking for events. You won't see any difference if most of the time the current script is waiting anyway, like in @petruvius 's example. Below is a script that really shows the difference (in this case, it's huge):

So WARP is useful for time-consuming calculations, at the cost of e.g. screen pictures and variable reporters not being updated for some time. Like @d4s_over_dt4 wrote: don't use warp around e.g. WAIT blocks and FOREVER loops, as that would unnecessarily slow down other scripts, big time!
