The One Billion Row Challenge (1BRC Original Java Challenge) is a fun exploration of how far modern .NET can be pushed for aggregating one billion rows from a text file. Grab all your (virtual) threads, reach out to SIMD, optimize your GC, or pull any other trick, and create the fastest implementation for solving this task!
Tested on a 3GHz 10-core Xeon W iMac Pro 2017.
