Yes sure but that's not the common experience for at least three reasons:

 1. it's the devel series so the release pocket gets republished all the
time
 2. you have apt-file installed and are downloading the Contents files.
those are always big
 3. you have deb-src enabled (this makes much less difference than the
previous 2 though)

If we want to make apt update quicker / lighter on resources we should
figure out if we can stop publishing some of the hashes (which entirely
dominate the size of the compressed package lists). We currently have 4
hashes in the lists (md5, sha1, sha256, sha512) -- I know Dimitri was
trying to get us to the point that we could stop publishing MD5 at least
but there are a few things out there that hardcode a dependence on it.
Maybe oracular is a good time to turn off some hashes and see what breaks.

Cheers,
mwh
