Items despawning in one minute

In Multiplayer Survival, items despawn in loaded chunks in one minute. I threw stacks of various items on the ground (jungle wood, andesite, dispensers, and diamond blocks), and then stood there and watched them vanish in a minute.This was tested on a server that was pure vanilla - no server side mods no Spigot, Bukkit, or anything else. No client side mods were used for this test either. This was also tested on a brand new world and no settings were touched.
