Disruptor Description

LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this it needs something special to achieve very low-latency and high-throughput with our Java platform. Performance testing showed that using queues to pass data between stages of the system was introducing latency, so we focused on optimising this area. Disruptor is the result of research and testing: cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so a framework which has "mechanical sympathy" for the hardware it's running on was create. This is not a specialist solution, it's not designed to work only for a financial application. The Disruptor is a general-purpose mechanism for solving a difficult problem in concurrent programming. It works in a different way to more conventional approaches, so you use it a little differently than you might be used to. For example, applying the pattern to your system is not as simple as replacing all your queues with the magic ring buffer.
