@terrydaktyllus1320 I have been running testing branch version with LTO overlay and everything optimized as much as possible. That has been my hobby essentially to try and find how to squeeze more performance. Always getting newest compilers that are not even in the testing section, and trying to do full rebuild with those. Gotta say that GCC 13 is looking pretty awesome, gained 5-7% on openssl algorithms on 8yr old dual core Intel vs. GCC 12 with the same optimizations that shouldn't even benefit from better parallelization etc. If you play around like me you are bound to get things broken, but it's pretty amazing how little issues I have had. So I would assume with stable version and sensible configuration it should be pretty easy to maintain.

@terrydaktyllus1320 In general hobbies don't have to make sense, as long as they are worth it for the individual. Though this dual core 2ghz laptop certainly benefits from this optimization. Compared to Ubuntu, which I also have for multiple reasons, it's so much faster. I have all the GentooLTO overlay optimizations, graphene, devirtualize at trans, no semantic interposition, ipa-pta, LTO with full size partition, Ofast etc. and I tested on the same go, before updating to GCC 13 and after, with all the same settings. It's especially impressive as the results cannot be from the new GCC having more optimization flags enabled on O2 or O3 level, now they both had the same flags. I would assume it's better utilization of AVX as we are talking about hashing etc. crypto algorithms. Sadly I didn't do more benchmarking as I was happy for seeing improvements on all of the countless algorithms and thus was happy to make the change.
