The bibliography files are between 4 and 5 MB.

4.5M Jan  8 13:36 readings.bib
4.9M Jan  8 13:30 readings.yaml

YAML is 3x slower than bibtex.

For my wrappers, I use a very fast (very strict) parser to subset the bibliographies to those used in the document. 

But I recently found myself again wishing I could switch to pandoc within the static blog generator (Pelican) but at 9s a page I can't.
