mmcilroy/disruptor_cpp

A CPP implementation of the LMAX disruptor for single producers

disruptor_cpp

A C++ implementation of the LMAX disruptor (https://github.com/LMAX-Exchange/disruptor). Goals are as follows...

• Provide similar or better performance characteristics
• Provide a similar interface to the java implementation

The current implementation supports only single producers

In its current state performance tests show rougly a x2 performance improvement over the java implementation as demonstrated by the output from the one_to_one_sequenced_throughput_test

License?

Hi, I think this is a rather nice and small implementation of Disruptor, but what's the license?
