I've fallen behind with my forum posts due to laser focus on v14.1 release (which is mostly done now...) Tim has said it better than me anyway (besides he knows much more about WordPress than me).
But I'd like to address your query regarding the default RAM settings from a TurnKey perspective. Basically the default settings are a bare minimum for testing purposes. We can't anticipate user's needs or desires so we basically went for as low a spec as possible. The default should work fine with the included plugins and a user or 2, but beyond initial install and testing you will almost definitely need to bump up the RAM. Depending on your specs you may also wish to bump up the swap too (although swap is MUCH slower than RAM).
Thanks Tim
