it's not about local cpu But if we make presto be on by default and the 
local performance is so bad for people with fast connections that it is 
almost unusuable then we have a problem.

So the idea is:

1. make performance not suck
2. maybe not make presto the default anyway.


Now #1 is obvious, I think :)

#2 is about the way someone would use the system. If I'm a place where I 
know the bandwidth is questionable then I figure immediately after install 
I can run: yum install yum-presto and be ready to go.

Or, we install yum-presto by default but disable it. So the first thing 
someone with bandwidth issues does is enable the plugin.


i think that's what this is all about.
