are you sure that deriving itself costs a lot? I would expect that
deriving itself is reasonably cheap, but results in a lot of
complicated (e.g. recursive) code that later analyzes have to go
through...

http://ghc.haskell.org/trac/ghc/ticket/9557 and tickets linked from
there are also relevant. In fact, there is even a keyword for this
meta-issue:
https://ghc.haskell.org/trac/ghc/query?status=!closed&keywords=~deriving-perf

Greetings,
Joachim
