Hello openSUSE! Talking about benchmarks, I spoke with Product Management earlier today, and we want to have data. PM seems to be expecting a larger gain than I see mentioned here. So the plan is to run a benchmark with some test suite (perhaps https://www.phoronix-test-suite.com/ ?). As of now, SUSE:ALP does not seem to be built with any -v3 flags. Once this is the case, we can use such an image and compare it to, e.g., v1-based TW minimal install. I expect that this will be later in September. Another outcome: We have to have a community -v3 ALP image, to support the non-paid to paid "seamless" migration use case for ALP. As mentioned before, PM doesn't block us from Rebuilding ALP as v1 or v2 in an openSUSE:Step- like fashion (this was also discussed on Rel-eng call two weeks ago or similar). Doug also had an idea to ask via survey@ who has -v3 hw available etc. So perhaps that would help. Investing into -v2 ALP rebuild will take some effort, and I want to make sure that such investment is backed with data and also understand the gain, etc. Lubos On Fri, 2022-08-05 at 07:59 +0200, Dan Čermák wrote:

Over the weekend, I have quickly gathered some SPEC CPU benchmarks results comparing the different x86_64 versions:
thanks, very interesting results. I admit this gain is even less than I expected.
Yes, the gain is small, but a few percent gain will result in e.g. HPC users to pick another distribution. But yeah, the gain in these benchmarks is really surprisingly small.
Cheers,
