GCC 11 PGO With The AMD Ryzen 9 5950X For Faster Performance
Out of 54 different tests ran, making use of PGO certainly led to higher performance in the far majority of them... In the cases where the PGO-built benchmark didn't lead, the results were all a wash and within the margin of error.
If taking the geometric mean of all 54 benchmarks, making use of GCC 11 profile guided optimizations on this Ryzen 9 5950X system was leading to around a 12% improvement overall. Apache HTTPD enjoyed the largest gains for simple, static website serving while AOM-AV1, SVT-AV1, Himeno, NCNN, and other software was seeing improvements from a couple percent up to around 10%.
