perf

[Cris]

Noticed some issues on adding some deps.

chokidar: kills CPU perf, futext thrashing, primarily what it's doing with readdirp, it's "choking" it up
natural: memory hit seems too big just for some stuff we might not need. See if we can shift to another string tokenization / stemming method or library

Should be able to replace chokidar with fs.watch ( I think )
