Those wanting to see more of these early GCC 11 tuning benchmarks on various workloads can continue checking them out via this OpenBenchmarking.org result file. GCC 11.1 as the first stable GCC 11 compiler release should be out in March~April so you can expect to see more compiler benchmarks on Phoronix leading up to that annual release.
