It’s been a few weeks since I last wrote about the aeson library for working with JSON in Haskell, but this isn’t because I’ve been idle. In fact, just tonight I put out a new release. Where the previous releases focused on parsing performance, this one focuses on encoding performance.

And the performance news is good: on real-world data, I’ve improved encoding performance by about a factor of 4. Why don’t we let the graphs do the talking.

Enjoy!
