Extreme TPS lag when using high Lunge levels with Unbreaking

Putting high levels of Lunge on a spear alongside Unbreaking and then performing the jab attack/lunge effect causes extreme TPS lag when the level of Lunge exceeds about 14 or so.

Steps to Reproduce:

• Use /give to obtain any type of spear with a high Lunge enchantment level (14-15 perhaps), as well as any Unbreaking level

  • Example command:

    /give @p netherite_spear[enchantments={lunge:15,unbreaking:1}]

• Left click to trigger the jab attack of the spear

• This will cause the server to freeze for a while. If not, try increasing the Lunge level.

• After freezing for several seconds, the lunge still occurs as expected.

Note: There seems to be no lag up until ~Lunge 12, at which point it is barely noticeable, then at 13 it gets slightly worse, and >14 causes extreme lag.

• These numbers may be dependent on hardware

Expected Result:

The jab should trigger instantaneously and without lag, as it does with lower lunge levels/without unbreaking.

Actual Result:

The server lags excessively after the jab is triggered (note: no client FPS lag), causing a freeze in TPS (visible in F3+2 profiler) for many seconds
