Gonna drop this here: https://openbenchmarking.org/result/...TJ-OSBENCHSE20
This morning I ran the phoronix pts/osbench benchmark across five GCC versions (7, 8, 9, 10, 11) on my Ubuntu 20.04 LTS on the same exact kernel (5.4.147) and system settings, etc. Basically compiled, benchmarked, compiled, benchmarked, etc.
Winner for my i5 Haswell.......drumroll......more...drumroll....... gcc 9.3.0 on Ubuntu 20.04
I had a hunch going in, but I'm glad I finally ran my own benchmarks on my *own* system (this is important. Michael can run his, but means jack if your system doesn't exhibit the same results).
Having said that, these are just 5 benchmarks. But for me, important indicators of overall OS performance (create processes, create threads). Sure, we're talking microperformances, but that's what we're here for baby. We're power usings. Power to the power users.
Anyways, don't want to derail the thread. But wanted to throw this out there. Cheers.
