Howdy all,

I finally had a chance to run some benchmarks this morning.  I used ab 
to hit my local machine.  I was testing 100 concurrent connections for 
two minutes.  The straight namespaces/noNamespaces files are run against 
the bookmarks app's default page.  The loadClass-sql-* files were calls 
that did a straight start() followed by a 
loadClass('Sql')/loadClass('Solar_Sql') while the bookmarks-* files are 
against index.php/bookmarks.  These are all with a namespaces array of 
Solar, Domain51.

Using the simplest form - loading a single class, it looks like there's 
a 5% hit in performance.  Using the bookmarks app, it looks like there 
was a 13% hit.  This just proves foreach() hurts anyway you shake it.  
I'm try some tweaks and see if I can get it better performance out of 
this.  If I can keep both under 5%, I'd be happy.
