• About

simdzone is a high-performance DNS presentation format parser. It leverages instructions found in modern processors to significantly improve throughput for operations like zone loading.

simdzone started life as a research project to improve zone loading performance in NSD, but is maintained as a separate project so it can benefit other projects as well. The project provides a convenient, liberally licensed, thread-safe library for deserializing DNS RRs in DNS presentation format. Alleviating developers from having to deal with all the complexity and intricacies of the format.

simdzone strives to be a reference implementation for emerging standards. The minimalistic design allows for quick integration and prototyping. The fact that is used by NSD ensures quite a respectable user base and real-world testing. We hope to attract users and contributions from interested parties.
