The limited data I've seen suggests the download speeds people get from the substitute servers vary a lot depending on their internet connecting peering and location, so it's quite hard to consider this in an abstract sense. Some people already get substitute download speeds that saturate a gigabit connection, while some don't. There has been work on setting up mirrors though, e.g. see [1] for some information and data on how these work for different people. 1: https://lists.gnu.org/archive/html/guix-devel/2023-05/msg00290.html --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKlBAEBCgCPFiEEPonu50WOcg2XVOCyXiijOwuE9XcFAmUpGYlfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDNF ODlFRUU3NDU4RTcyMEQ5NzU0RTBCMjVFMjhBMzNCMEI4NEY1NzcRHG1haWxAY2Jh aW5lcy5uZXQACgkQXiijOwuE9Xe6eA//QQIVZMZCmtPoDTaQsnhi9nSA0Cx7QaUP qYpn3Jklw8kd18ty2HOIvP3FWDy2u4yA5aEdwZTxjLHSm27U7cBf4Ura8ITQkUe4 eiArdKnaARIAR3W3QMizeqgHtQmoeDXXvkkUdRIIElpDMNwDe/jS61Q4tyYBVreN 9BCy1RLB+ytjjJvCEpVSyt8Kc905uHe004EEKoo1wNIBODoDd2uQdmvr/yuoK4Zs Xdb4I2SwD0l9dhNxfeN4hCCAWeTgA3Bw1L1Jl06hmptibyqaKizot/80URAIXp3q Up1lZoGU1psWXrjIzLvzpwgQmHWaHQ2yEIwxYMCN/hxUUB8go4U3QxUyfb6/plFl 3qtrgrfClenMgildlqzg54H5/FMfNPfrf+RdiiTyBQr0KRcw+igBvBns4tBGNtY+ hSU8taLo9Xbkoi1cqKYGdFb+CbzYyJgcZA+8kpe5/h/o971FaTvoBTClERIO6l1e T43gHX9haMI2ouEocQehL4JI3KEM0EAhQ6lMaWZ4If0+v+NQd6e5Sv+DIxk5HP27 xhmNuDPlHq/n/1ZvPQw9W+8N61O6+wW/t6FkD6dUygVl/pZ4/z3TkUuy5y85b4h/ bRwclV+dLkaTBsThiyEwjYh2CaBhuu0avezoG3hGHTKYeUWVYrnTH1JDhne9pke9 tiEl3JURWyY= =5Zx/ -----END PGP SIGNATURE----- --=-=-=--
