inefficient frameworks

I’d like to object to that. Frameworks are often built by dedicated and paid developers, so they tend to be above average in terms of efficiency. But being frameworks, they have to facilitate lots of use cases, so they also tend to be bigger than what you would write if you had 6 months to roll your own. And 36 more months to kill all the worms that got out of the can, to mangle a proverb.
