Finding and fixing performance bugs in real-world software is a tricky task. It involves exploration and experimentation. During this talk, you will discover several performance issues found while working on Dotty as well as tools used to diagnose those issues.
Areas to be covered include application specific and low-level performance counters as well as micro-benchmarking and regression testing. This talk is not Scala-specific and should apply to most statically typed languages on HotSpot.

Dmitry has been working on Scala since 2013 when he joined Martin Odersky's research lab at EPFL, working on ScalaBlitz, macro-generated collections for Scala. Since 2015, he has been working on the Dotty Compiler. He designed Mini-Phases, ported the JVM backend, implemented support for Java 8 lambdas and default methods along with various other parts of the compiler, including the pattern matcher, lazy vals, tail recursion transformations and parts of erasure and mixin composition.He is currently working on implementing the Dotty Linker, an optimizing compiler based on Dotty.
