Recent commits make it much slower

[thenewvu]

Thank you for making this awesome plugin!

I have updated the plugin and it's much slower than before, especially comparing to this revision: dea5030 (which works only in the current buffer)

I tested it on one of my longest jsx file, it's slow when scrolling to lines with deep indent depth. It was fine with revision dea5030.

I'm not sure what to provide to help inspect the issue, please let me know if I can help.
