Repeat with slow on iOS?

If you run this script on the desktop with all the lines enabled... it takes 395 millisecs
If you run this script on the desktop with the three lines indicated, disabled... it takes 0 millisecs... the same in the iphone simulator.
on mouseUp
   put the milliseconds into theStart
   repeat with x=1 to 100
      put "a"&x into tVeld
      --enable fld 1
      --put empty into fld 1
      --set the backgroundcolor of fld 1 to white
   end repeat
   put the milliseconds - theStart into fld 1
end mouseUp

be well
