Performance for long DOM text #191

Closed TomThak closed 8 years ago

TomThak commented 8 years ago

Hello, I have serious problems with performance of the plug in, when there is a really long DOM document. If I fix like 3elements and I have really long parent with many texts like legislation document, it totaly freezes any browser if I apply the plug in.

Performance should be no different than using position: fixed as long as you're not telling it to update every scroll frame. Can you show the code you're using to initialize the library?

Closing this, open again if you have more information.

For anyone curious about performance, make sure you're not using recalc_every: 1 since it causes a lot of work to be done in the scroll handler.
