JavaZone 2010 - Do you really get Memory?
You should attend this talk if any of the following questions give you pause:
- How slow is memory?
- How pagefaults happen and what do they mean?
- Why swapfile and Java don't get along?
- What does "synchronized" do besides locking?
- What does volatile really do?
- What do you need CompareAndSwap for?
- Why GC doesn't scale well and what is being done about it?
- What hardware developments can change the JVM game?
To answer those questions I'll build a simple CPU model in Java to illustrate the concepts in a comprehensible way.
