windows default iconDisruptor Publisher's description

LMAX aims to be the fastest trading platform in the world.

LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this we needed to do 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.

The Disruptor is the result of our research and testing. We found that cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so we created a framework which has "mechanical sympathy" for the hardware it's running on, and that's lock-free.

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.

What's New in This Release:

Create new MultithreadClaimStrategy that works between when threads are highly contended. Previous implementation is now called MultithreadLowContentionClaimStrategy
Fix for bug where EventProcessors weren't being added as gating sequences to the ring buffer.
Fix range tracking bug in Histogram
