Summoning item Creats unbearable Lag

When running this exact command:

/summon ~ ~ ~ Item

The frame rate of my game goes to 0.

Note, I had my settings to be the fastest possible, in an air only world, so I was getting up to 180 FPS, and it would drop to 0 with 1 of those items.

After including:

{Item:{id:1,Count:1}}

The item would spawn with no lag whatsoever.
