• FYI: Variability in build times for qt6-webengine-6.10.1_2 on ampere4 and ampere5

    Prior numbers were based on just (nearly?) from scratch builds of the port-packages. This illustrates also with much smaller overall builds.


    Examples from official ampere4/5 builder records:

    Built+Failed for the below:
    ampere4 143arm64 1475+107 vs. 35759+111
    ampere5 150arm64 1476+130 vs. 35748+127

    ampere4 143arm64 qt6-webengine-6.10.1_2 20:10:22 vs. 27:06:38
    ampere5 150arm64 qt6-webengine-6.10.1_2 29:54:49 vs. 41:25:10
    approx. ratio (ampere5/ampere4) 1.48 vs. 1.53

    So the shorter times are from much smaller incremental builds
    and the larger times are from (near?) from-scratch builds.

    ampere4 and ampere5 are reportedly nearly identical systems --so not
    expected to have large performance ratios if the same work is being done.


    Note: Various other long build time port packages do not have such large ratios.
