From the wiki: Hoppers have a “transfer cooldown” time. After pulling and/or pushing items, a hopper waits 4 redstone ticks (0.4 seconds, barring lag) before pulling or pushing again (a transfer rate of 2.5 items per second, barring lag).

What happens if a hopper is powered?
The hopper underneath is powered so that it cannot remove items from the top. Note that the top hopper must be pointed away from the bottom hopper, otherwise it will push items into the bottom hopper. When enough items fill the top hopper, the bottom hopper is unpowered so that it can remove the extra items.
How often does an item pass through a hopper in Minecraft?
An item will pass through a hopper every .4 seconds. A Minecraft tick is 1/20th of a second, or 0.05s.
How many ticks to get one item through Hopper?
So, that means every 0.4s 8 ticks occur. Therefore, you will need to wait 8 ticks in order to get 1 item through a hopper. This holds true for Bukkit servers as well. Note that redstone devices run on 1/10 second steps, not 1/20.
How do you block hoppers in Minecraft Java?
As both hoppers try to push their first item each way, only one ends up moving. To make hoppers pass the whole load before starting to pass it back, you need to block the next (opposing) hopper until your current one is empty.
How do you make a hopper pass the load?
To make hoppers pass the whole load before starting to pass it back, you need to block the next (opposing) hopper until your current one is empty. The standard way (that you mention yourself) is measuring the contents of the current hopper with a comparator, and feeding this signal into the next hopper.
