Most important for me: you only activate what you need: lighter = faster. I'd recommend installing just the bare minimum of optional packages at first. Note: I have it installed on MAMP and MAPP stacks and on Ubuntu server with Postgres. It's relatively easy to modify the templates and CSS to make it look completely custom. Also, very easy to translate. Very flexible system geared for speed.
2.6.1 and 2.7 didn't install on wamp... lost interest on this cms.
