We recently ran an experiment using KSP at airbnb I did some analysis on the results: https://docs.google.com/document/d/1zqQ5cMeucvAZtzN94YIcryvaNK_8KiJwF0Uyof4x5rw/edit# Quick summary: • ~660/900 modules were eligible to use ksp • KSP helped most builds by about 10% in most percentiles, but dropped the performance of P95 builds P95 drop in performance is likely from remote cache incompatibility and worse incremental compilation than kapt (ksp.incremental.intermodule=true just landed to address this)

Thanks for sharing! The release containing

ksp.incremental.intermodule

is coming in a couple of hours. Please stay tuned 😄

Excited to try it out!

Yes. We'll prioritize it and make sure the fix included in next release.
