Slime Killing Chamber Benchmarks
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.
