Here’s an update, 1.5 month later. This time I’m looking at nginx logs
covering Feb 8th to Mar 17th and using a laxer regexp than in the
message above, here are the gzip/lzip download ratio for several
packages:
--8<---------------cut here---------------start------------->8---
ludo@berlin ~$ ./nar-download-stats.sh /tmp/sample3.log
gtk%2B-3: gzip/lzip ratio: 37/3255 1%
glib-2: gzip/lzip ratio: 97/8629 1%
coreutils-8: gzip/lzip ratio: 81/2306 3%
python-3: gzip/lzip ratio: 120/7177 1%
r-minimal-[34]: gzip/lzip ratio: 8/302 2%
openmpi-4: gzip/lzip ratio: 19/236 8%
hwloc-2: gzip/lzip ratio: 10/43 23%
gfortran-7: gzip/lzip ratio: 6/225 2%
--8<---------------cut here---------------end--------------->8---
Interesting findings...
Conclusion? It still sounds like we can’t reasonably remove gzip
support just yet.
I’d still like to start providing zstd-compressed substitutes though.
So I think what we can do is:
• start providing zstd substitutes on berlin right now so that when
1.2.1 comes out, at least some substitutes are available as zstd;
• when 1.2.1 is announced, announce that gzip substitutes may be
removed in the future and invite users to upgrade;
My personal substitution servers runs with lzip + zstd, so no gzip. It
works fine, but I didn't had any "legacy" users. Although zstd is only
0,6% of lzip in regards to total downloads over the last months...
