It's hard to tell anything conclusive without time profile of the build,
but here are few general comments and observations
P2 treats metadata and artifact repositories separately, this is why you
see "Adding repository ..." message twice. Nothing to worry about here.
P2 repository metadata can get quite big, so depending on your hardware
it may take a second or two just to read and parse content.xml file from
local disk.
Due to a bug (or misunderstood feature) in p2 3.6, it always checks if
remote repository has p2.index file. I was told this file was optional
and failures to access it were silently ignored.
We have integration test [1] to make sure Tycho build works offline and
I double checked by build and rebuilding m2eclipse-tycho with cable
unplugged.
