Re: [tycho-user] Pack200'd artifacts w/o unpacked ones?

[Nick Boldt <nickboldt@xxxxxxxxx>]

It's more load on the client if you're installing from an offline
update site zip which includes both packed and unpacked artifacts,
because the zip is 40% larger than it needs to be. Users would be
downloading both sets of artifacts, then only ever using the pack.gz
ones.

So your suggestion is build the site w/ all the jars (packed and
unpacked) then use p2.mirror to create a new, second site which
filters out the unpacked ones? I suppose that would be better than
building the whole site a second time (minus the profile to enable
pack200) and getting a timestamp that's a few minutes later.
