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. -- === Mark Millard marklmi at yahoo.comhome | help
