Beware: wget shows the “instantaneous” throughput, whereas Guix shows the average throughput since the beginning. So to be sure, you need to make a full download. Also, please compare not only against ‘guix substitute’ but also against ‘guix download’. Regardless, I don’t see anything like that here. Commit c822fb8 may help a bit; could you retry? Commit 7623848 helps for source derivations and ‘guix download’ for Guile <= 2.0.11, but it shouldn’t make any difference for ‘guix substitute’. Thanks for the report, Ludo’.
