+It's really fast. 
+
+Using [alba benchmarks](https://github.com/thoughtbot/alba/tree/main/benchmark),
+`props_template` only falls slighly behind `panko` while being feature packed.
+The `Props::Base` [class](./lib/props_template/base.rb) that `props_template`
+uses is the fastest among all JSON serializers.
