Why I see zypper is going to download a new kernel I go make a pot of coffee.
Much depends on mirrors available in or near your location. And your own downstream link of course. A kernel is about 50Mb, for me it takes just over a second, from a local Swiss server. From Germany, 8seconds, from Sweden, 1.2seconds, from Bulgaria, 38sec.
Oh FOO! Although I'm paying for a channel many, many times faster than this, the best I ever get on a long download such as a kernel update using zypper is 630 KiB/s or so. More typically an average under 550 KiB/s. On smaller downloads or on a bad day I might be running between 20 and 30 KiB/s. The observations by JDD and Fraser_Bell are very apropos here. oh, just done a update on a "quiet sunday" Retrieving: kernel-macros-4.17.0-2.1.xxx.noarch.rpm ....[done (407.8 KiB/s)] Well Foo to that performance too. It looks like that came from http://ftp2.nluug.nl/os/Linux/distr/opensuse/repositories/Kernel:/stable/sta... according to the log file. All the way across the atlantic when there is a host of servers within a few hundred km of me here in Toronto. There is something VERY wrong with the algorithm. A ping gives me rtt min/avg/max/mdev = 108.263/807.891/1331.145/417.512 ms, pipe 2 traceroute shows crossing the Atlantic to London but after that its "* * *" all the way the limit of 30 hops. A more local site, Waterloo is just 113km to the west of Toronto. http://mirror.csclub.uwaterloo.ca rtt min/avg/max/mdev = 38.311/534.919/1138.478/444.775 ms, pipe 2 Traceroute puts it just 16 hops away, but, sadly, most of that is over Rogers network :-( That's always going to be the limiting feature in this part of the world.
