I've noticed over the years that optimization techniques could be mutually beneficial across many package managers, but the matrix of which PM supports what is fairly sparse: we usually only find out about new techniques from talking to each other, or happening on the same ideas.

My goal with this talk would be to get at least some of what I think are the newer techniques out there for getting stuff to go fast, with reduced memory usage, because I think it's important for us all to talk to each other and make sure we're all using the state of the art.

Some examples:
* Take advantage of Copy on Write filesystems
* Content-addressable package storage for deduplication and fast access
* Lazy fetching from a global cache
* Optimizing server-side package representations/endpoints for maximum cacheability/CDN-ability

I won't go too deep into any of these, but I'll try and at least give a solid idea of what each of those are, and their advantages, as well as how to learn more.
