Comment:

 In https://github.com/bos/aeson/pull/335#issue-127344930, RyanGlScott
 mentions:
 > To test out the improvments, I did a very fast-and-loose profiling of
 the time and memory it takes to compile `pandoc-types` (a package known to
 be affected badly by the aeson-0.10 compilation regressions).

 > The total wall time went from 10 minutes to under a minute, and it went
 from using 3 GB of RAM (and thrashing my laptop mercilessly) to about 500
 MB of RAM.

 pavolzetor: make sure you upgrade to the latest version of `aeson` to get
 those improvements.

 The //real// problem with Generics compile-time performance it still
 tracked in #5642.
