I ran the tests on a graviton2 instance and saw the improvement as expected/desired:
length | before (MiB/s) | after (MiB/s) | delta ----------|----------------|----------------|---------- 32768 | 233.19 | 247.61 | 6.18% 65536 | 443.44 | 468.68 | 5.69% 131072 | 852.52 | 895.00 | 4.98% 262144 | 1630.48 | 1704.48 | 4.54% 524288 | 2480.18 | 2601.47 | 4.89% 1048576 | 3900.73 | 4112.08 | 5.42% I'll try to get some people to test some other arm64 systems before calling this verification-done though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1951032 Title: AArch64: Backport memcpy improvements To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1951032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
