GCC 10 Link-Time Optimization Benchmarks On AMD Threadripper

How do you get 5.4 on 19.10? Custom built? I've run a 48-thread compile of our own product on the newly arrived 3960X, pretty darn sweet. It usually compiles for around 30 minutes, on this beast it went down to 6 lol.
Currently I run it with 18.04 + hwe-edge (5.3); besides that stupid MCE bug (btw thanks for the workaround!), it seems to run solid so far.

Granted there seems to be some regressions that need investigation but other than that, LTO looks like a boon for a lot of use cases.Last edited by milkylainen; 07 January 2020, 05:04 PM.

Hm these benchmarks do not seem to be too impressive, but IIRC Firefox does benefit quite a bit from it, which AFAIK is one of the reasons it performs relatively well on Fedora compared to other distros (see https://www.phoronix.com/scan.php?pa...os-50cpu&num=2)

GCC 10 Link-Time Optimization Benchmarks On AMD Threadripper
Phoronix: GCC 10 Link-Time Optimization Benchmarks On AMD Threadripper
Stemming from the recent news in Fedora 32 potentially LTO'ing packages by default for better performance and not yet having checked on the Link-Time Optimization performance of the in-development GCC 10, here is a fresh look at the possible performance gains from making use of link-time optimizations for generating faster binaries. This round of testing was done on the AMD Ryzen Threadripper 3960X and is complementary to the recent Profile Guided Optimization benchmarks.
