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!
