Somewhat, but you're better off running 2.0 rules with 2.0 instead.  If
you're using the distributed rules, scrap your 1.9.x rules and migrate to
2.0 entirely.

Not really.  2.0 has a bigger memory footprint, but it's also about 18x
faster.  :)  If you're on a box with a small amount of memory, there is a
lowmem config option that can cut down on the memory usage.
