Description

This patch is a trivial optimisation of the toJSON() function in main.js

It provides a surprising speedup. For example, in my real-world app, it reduces indexing time of ~3,800 docs from 80 seconds to 60 seconds. And using the benchmark script I posted to dev@, I see:

2.877 -> 2.062 secs (3000 docs, emit one k/v per doc)
13.522 -> 7.585 secs (3000 docs, emit 10 simple k/v per doc)
19.049 -> 12.714 secs (3000 docs, emit 10 compound k/v per doc)
