What's the fastest slime killing chamber in Minecraft?

Soul Campfire with Powder Snow on top. Big slimes die in 102.80 ticks (~5.1 seconds), medium slimes in 33.50 ticks, and small slimes in 21.00 ticks. Tested in Minecraft Java Edition with 500 big slimes dropped from height into a contained chamber.

How fast does a Soul Campfire kill slimes?

A single Soul Campfire kills big slimes in 102.01 ticks (~5.1 seconds), medium slimes in 35.50 ticks (~1.8 seconds), and small slimes in 21.00 ticks (~1.05 seconds) in Minecraft Java Edition.

Does adding Powder Snow on top of Soul Campfire kill slimes faster?

Yes, for medium slimes: it reduces kill time from 35.50 to 33.50 ticks. Big slime kill times are nearly identical (102.80 vs 102.01 ticks). Small slime kill times are unchanged at 21.00 ticks.

How many slime killing chamber configurations were tested?

13 block configurations were benchmarked, including combinations of Soul Campfire, Powder Snow, Magma Block, Wither Rose, Campfire, Mud, and Cobweb. Each was compared on big, medium, and small slime kill times in Minecraft Java Edition.

Slime Killing Chamber Benchmarks

Q: How was the slime killing chamber benchmark tested?

500 big slimes were dropped from a set height with no fall damage into a contained killing chamber. Average time in ticks was measured for all big slimes to die, then for all medium slimes (split from big), then for all small slimes (split from medium). All tests were performed in Minecraft Java Edition.

Which block configuration kills slimes the fastest?

Methodology: 500 big slimes were dropped from a set height (no fall damage) into a contained killing chamber. The average time (in ticks) was measured for all big slimes to die, then for all medium slimes (split from big), then all small slimes (split from medium). All tests were performed in Java Edition.

^* Cobweb caveat: The cobwebs slowed the big slimes, causing all medium and small slimes to spawn directly on the killing floor where they could not jump. No medium or small slimes were spawned in the air and slowed by cobwebs. This makes the medium and small kill times not directly comparable to the other configurations.

This page compares 13 different killing chamber configurations for Minecraft slime farms. Each setup was tested with 500 big slimes in Java Edition, measuring the average kill time in ticks for big, medium, and small slimes. Soul campfires are the most effective base block, with powder snow and wither rose variations offering trade-offs between kill speeds for different slime sizes.
