Use an alternative JSON deserialization library

I've heard through the grapevine that one of our current constraints has been JSON size due to the limits of parsing speed. A fairly recent blog post I read actually points out two incredibly capable competitors:

• simplejson
• UltraJSON

See: JSON vs simpleJSON vs ultraJSON

Offhand notes:

• Both libraries seem to be consistently faster for loads.
  • This is significant beacuse we only do loads.
• UltraJSON generally seems to be faster than simplejson.
• UltraJSON has a C code dependency.
• simplejson is written in Python, but has an optional C backend for speed.

I think it would be worth experimenting with the two to see what kinds of gains we can get.

I've plotted the data from the blog post below.

Dumps

L’issue ne mentionne aucun fichier du dépôt, test ou point d’entrée ; commencez par localiser le chemin actuel de désérialisation JSON dans le plugin. Évaluez les chargements avec simplejson et UltraJSON par rapport à l’implémentation existante, en tenant compte de la dépendance C de UltraJSON, et documentez si les gains mesurés justifient une modification.
