Understanding Application Hiccups: An Introduction to the Open Source jHiccup Tool
Speaker: Gil Tene, CTO and co-founder, Azul Systems, Inc.
Does your application run fine most of the time, but occasionally "gets the hiccups"? Do you measure and recognize such hiccups and stalls if and when they occur?
In this Webcast, Gil Tene (CTO, Azul Systems) introduces simple, non-obtrusive methods for measuring and characterizing platform "hiccups" during application execution. Using the new jHiccup open source tool, Gil demonstrates and charts commonly observed behaviors of idle, mostly idle, and busy systems, as well as common workload types that experience outliers due to garbage collection pauses and other runtime-induced delays. After demonstrating how simple, non-obtrusive measurement can establish a clear "best case" baseline for any expected application responsiveness, Gil discusses the important things to look for in such measurements, as well as the common pitfalls experienced early in characterization attempts. Finally, using "Hiccup charts", Gil shows samples of how different runtimes, configurations and garbage collection techniques behave using platform responsiveness measures.
