Item travel very slow when using hoppers.

Hoppers don't spit out items instantly. Instead they wait until they are completely filled up and then spit out items. For example, if I put a stack of diamonds in the hopper the other hopper that the diamonds will travel to won't spit out the diamonds instantly. It takes a very long time for the items to travel long distances and I hope you guys can fix it in 0.14.1 or something. Thank you for your time!
