Apr 29: Understanding Garbage Collection by Matt Schuetze

Title: Understanding Garbage Collection – Inside the JVM. How GC works and what you can do about it, by Matt Schuetze

When: Apr 29, 6 - 9 PM (Presentation begins at 7 PM)

Food: We'll have pizza and sodas.

Plug: The RubyNation Ruby/Web Platform Conference is coming up on Jun 6-7! See rubynation.org

Description: Garbage Collection is an integral part of application behavior on Java platforms, yet it is often misunderstood. As such, it is important for Java developers to understand the actions you can take in selecting and tuning collector mechanisms, as well as in your application architecture choices.

 In this presentation, Matt Schuetze reviews and classifies the various garbage collectors and collection techniques available in JVMs today. Following a quick overview of common garbage collection techniques including generational, parallel, stop-the-world, incremental, concurrent and mostly-concurrent algorithms, he defines terms and metrics common to all collectors. He classifies each major JVM collector's mechanisms and characteristics and discuss the tradeoffs involved in balancing requirements for responsiveness, throughput, space, and available memory across varying scale levels. Matt discusses means to resume application scale to match modern x64 hardware capacities. Matt concludes with some pitfalls, common misconceptions, and "myths" around garbage collection behavior, as well as examples of how some good choices can result in impressive application behavior

    Hi Gray. Great presentation last night. You mentioned something about getting discounted tickets to the Ruby Nation conference. Do you have any more information on that? Thanks!

    What's the real capacity of the venue? I can't imagine that everyone who has RSVP'd will show up, but if the venue only holds 100 I should wait until I'm no longer on the waiting list.

      We set the capacity at 120 knowing that we will probably have 1/3 no shows. I counted last night and we had about 80 people with 119 people registered. So, this one worked out pretty well, especially since enough people unregistered at the end when they knew they could not come to empty the wait list.
