To be fair, we should only compare the size of *.jar which have matching .jar.pack.gz. So far it's not the case

5631
mbarbero@build:~> find ~/downloads/releases/photon/201806271001/plugins -name "*.jar.pack.gz" | wc -l

We've twice as many .jar than .jar.pack.gz.

Ah, I just noticed that autogenerated source bundles are not packed. Interesting.

 

So:

mbarbero@build:~> find ~/downloads/releases/photon/201806271001/plugins -name "*.jar.pack.gz" -print0 | sed -e 's/jar.pack.gz/jar/g' | du -hc --files0-from=- | tail -n 1
1,2G total

So we're talking 1.2G vs 741M for a ~ half of the repo.

FWIW, from the download location itself.

mistria@build:~/downloads/releases/photon/201806271001/plugins> du -ch *.jar

So it's ~60% less, and Lars experiment with gz shows that gz keeps the same ratio after compression.

So are we ready to increase the download ratio caused by updates to download.eclipse.org by 115% ?
