a flamegraph of no-op compilation run using sbt 2.0.0-RC-6. it shows a big column in the middle, indicating that most of the time is spent doing one thing, which in this case is running sha256Hash function.
🦃 during sbt 2.0.0-RC7 development, I attempted some perf improvement to fix the no-op compilation perf regression that was reported. since RC7 is out, I can finally post 'sudori part 8: no-op compilation performance' (didn't write this on Thanksgiving)

a screen capture from the 'sbt 2.0: go big' talk. Vision sbt 2.0 An idea of the ultimate build tool 1. Simplify build.sbt DSL 2. Use Scala 3 constructs 3. Caching 4. sbtn by default 5. Continuity
a screen capture from the 'sbt 2.0: go big' talk. sbt 2.x: test results will be cached on CI
caching is IO-effect-hard At least as hard as the IO problem someTask := { val conv = fileConverter.value val out: java.nio.file.Path = createFile(...) conv.toVirtualFile(out): xsbti.HashedVirtualFileRef } This will just memorize the file path and hash but won't materialize the file on disk someTask := { val conv = fileConverter.value val out: java.nio.file.Path = createFile(...) val vf: xsbti.VirtualFile = conv.toVirtualFile(out) Def.declareOutput(vf) vf } Def.declareOutput(vf) will materialize the file on cache hit
