Workshop : Java Performance Workshop

Location : Seacliff A
Day of week : Friday
Duration : 9:00am - 4:00pm
This comprehensive one-day workshop is packed with techniques that have been proven to improve your ability to find and fix performance bottlenecks. What you won’t find are tips and tricks that will be obsoleted with the next release of Java. Instead, the course focuses on a methodology that has evolved from years of experience solving performance problems found in a variety of languages running on a number of different execution platforms.
 
This workshop contains several exercises each taken from real-world problems and designed to challenge your thinking. During this day, you will learn things like:
  • Quickly identify the root causes of poor performance in your application
  • Eliminate conditions that will prevent you from finding performance bottlenecks
  • Find critical supportive evidence before deciding on a potentially expensive course of action
  • Find performance issues before they make their escape into your production system
 Topics this course may cover include:
  • Defining performance and performance tuning
  • Psychology of performance tuning
  • Performance tuning methodology
  • Performance tuning model
  • System monitoring
  • Response time budgeting
  • Usage patterns
  • Test harnesses
  • Load, stress, and endurance testing
  • Micro and macro benchmarking
  • Analysis of benchmarking results
  • Factors that affect benchmarks
  • Benchmarking exercises
  • HotSpot internals, monitoring, tools, & tuning
  • Memory management
  • Garbage collection basics
  • Object Lifecycle
  • Monitoring & analysis garbage collection
  • Inter-process communications monitoring
  • JDBC monitoring
  • Java Management eXtentions (JMX)
  • Thread profiling
  • Execution profiling
  • Thread monitoring
  • Memory profiling
  • Memory leak and loitering objects diagnosis and repair
  • Thread dump analysis
  • Case Studies
  • Monitoring and profiling exercises

Talk : The Trouble With Memory

Track : Bare Knuckle Performance
Location : Bayview AB
Day of week : Tuesday
Duration : 11:50am - 12:40pm

It is our experience that 60-70% of all the applications we analyze incur a performance penalty due to how it consumes and/or retains memory. Yet if you ask people what is their biggest performance headache it’s unlikely that they’d recognize memory as being #1. I have been involved in analyzing numerous applications for just these kinds of issues and in this session, I will cover the tell tale signs and symptoms that your application is one of those suffering from some sort of memory issue.  I'll discuss what steps you can take to cure this problem and will also cover how the JVM can both help reduce the memory ~strength of your application.  What should you do?"
