Re: [python-committers] CFFI is slow

  2. How important is this speed difference?  I suppose the answer,

  C library, and how long you spend in the routine when you get
  there.  Certainly a benchmark for library X is a worst-case
  scenario; in real-world code, for most libraries, perhaps the
  performance of the glue code isn't crucial.

Several of the early adopters of library X were the sqlalchemy people, who absolutely had real-world issues.

  Of course this is all academic.  I absolutely don't think we can
  get rid of the C API, or even modify it in any meaningful way that
  would let us abstract away implementation details like reference
  counting.  As I said in my original email, this magic wand simply
  doesn't exist./arry

Sorry for misquoting, indeed you said that. I was a little concerned that CFFI was mentioned by several people as a solution and wanted to highlight the drawbacks.
