CDN links are much faster in average. https://www.kernel.org/
links shows usually less than 10 MB/s, while https://cdn.kernel.org/
could give up to 200 MB/s and usually shows speeds much higher than
10 MB/s. Also, 'xz' archives are 30-50 MB smaller than gzip ones.
It takes a bit more time to unpack them, but it's negligible in
compare with download time.
For exmaple,
linux-3.16.54.tar.gz - 122064395 (116M)
linux-3.16.54.tar.xz - 81057528 (77M)
'xz' archive download via CDN link is the default way for kernel
downloading that provided by the kernel.org.
Some exmaples from Travis builds:
Before:
100%[==>] 122,064,395 3.11MB/s in 36s
(3.23 MB/s) - 'linux-3.16.54.tar.gz' saved [122064395/122064395]
100%[==>] 157,764,715 7.16MB/s in 24s
(6.28 MB/s) - 'linux-4.17.14.tar.gz' saved [157764715/157764715]
After:
100%[==>] 81,057,528 95.0MB/s in 0.8s
(95.0 MB/s) - 'linux-3.16.54.tar.xz' saved [81057528/81057528]
100%[==>] 102,195,552 218MB/s in 0.4s
(218 MB/s) - 'linux-4.17.14.tar.xz' saved [102195552/102195552]
