High Performance Erasure Coding - the Story so Far - Connor Fawcett, IBM We have been working to improve erasure coding performance, such that it performs almost as well as replica 3 configurations for all configurations, including block and file. Our aim here is to expose the wider Ceph community to the changes we're making to erasure coding and pave the way for wider adoption as we increase visibility of performance improvements over time. In this talk we will share the latest news on erasure coding improvements and include performance benchmarks on the latest experimental code.
