Sure, and 2.5 seconds _extra_ is a long time.

Here's three:

* Download from multiple mirrors simultaneously
* Do the transaction in parallel so that you're downloading the next
depsolved set of updates as you're installing the first
* Have better control of the cache format so you don't need to keep
three files in sync just to update the primary and then depsolve.
