[llvm-dev] OT: Cloning llvm repo over low speed connection != fun

[C Bergström via llvm-dev]

I remember reading all those examples about how a big repo isn't an
issue and when sitting at some ${LOCATION} I have 1010101010Gbps and
it takes like 30 seconds.. Well.. that may be true when I'm at home,
but I'm not.. and this laptop doesn't have llvm sources installed..

So real world feedback of the pita it can be..
/* Side rant - I wish I didn't even need the llvm sources. I just want
to build libcxxrt */

/* Yes I'm about to do the smarter thing and fetch a shallow clone or
try to get the tarball snapshot from github.. I did however want to
show an example of how big repo on non-corporate infrastructure can be
a challenge. I'd hate for some ambitious community dev to run into the
same thing and turn away as a result */
