Extreme Profiling: Digging Into Hotspots by Nitsan Wakart

Hold onto your hats! On bunny ears, if you like. Diving down the rabbit hole we will explore a host of advanced tools for analysing performance hotspots in Java code:

  • The Code is a Lie: why the line of code indicator is broken
  • JMH perfasm: looking at microbenchmarks under the microscope
  • JITWatch: digging into compilation process and stages
  • Solaris Studio: Not just for Solaris! performance counters and more!
