Talks at YOW!

Disruptor 3.0: Details and Advanced Patterns - YOW! 2013 Brisbane

Even a tool, like the Disruptor, that comes out of the box with great performance, it is possible to apply an understanding of the problem and a some mechanical sympathy to make the software run even faster. In this talk I will demonstrate an advanced technique of applying the Disruptor to two specific, but very common use cases to improve throughput and decrease latency. The cover of the CPU will be lifted to examine a number of hardware metrics with the intention of understanding where the additional performance comes from.
