There's nothing to improve, the item collecting is already happening at the very second the item spawns it couldn't be faster than that
What you can do is place multiple chesthoppers with hoppers attached to them, the whole point of chesthoppers is to reduce lag and size of farms, if we increased the hopper transfer speed we'd encounter in multiple other issues such as breaking current farms, breaking timers, adding load hence increasing lag spikes that we're trying to remove
