Respawning after death causes massive lag spike

The bug

When the player dies, a massive lag spike occurs which makes the game very laggy and causes biomes not to "display" even if chunks are loaded.

How to reproduce

Press Alt+F3 to display the F3 menu with the graphics
Run the /kill command
Look at the graph on the left and observe the sudden massive lag spike
