Ok I got LAMP going on the Pogo and have a joomla sample site working on it if anyone wants to see it in action.
I figured Joomla would be a good test for the box. I do not have Joomla's built in caching enabled for the site, so it is doing the database querys and building the page for each visitor.
This is coming off of my comcast connection.

It is also serving the html compressed, so that is another little hit on the device to compress the page before delivering it.
Apache and php do this html compression by default nowadays. If you want to learn more about it, here is a company that sells http compression for older Windows servers:
http://pipeboost.com They have a realtime acceleration report where you can view the benefits of html compression with a web site that you choose.
--Incidentally, I learned about html compression way back when -from the anandtech web page. Anandtech was a high profile customer of Pipeboost.
Using htop to monitor the CPU of the Pogo, (more informative than the standard linux top utility) I get a 100% utilization spike when accessing a joomla page for about 1 second and then the CPU goes back to 1-2% utilization.
I now have 100 MB of ram utilized of the 256 megs thus far.
