So, having run Octopress for a few days, I suppose it’s time I comment on it.
My interest was initially piqued by the static site speed and resistance to heavy traffic. The former, in particular, caught my eye after I noticed how long it took me, on a fat pipe, to load any pages. Even with WP-Supercache I found that pages tended to expire before anyone saw them.
My webhost, along with logging for bandwidth or similar restrictions, logged CPU usage.
