Please provide a codepen or jsfiddle code example of that problem. Chosen doesn't support ajax loading of options by default so it's not clear what you are doing.

Your performance problem is most likely on the way you add/manage those options and not on chosen itself.

A very simple example with > 3900 options loads 'instant' on my machine (also very dependent on clients machine performance, of course).

There is already a canonical issue for "performance issues with very large lists", but that's for lists in the 20,000+ range. Closing this as either a dupe of that (#2580), or something else happening (@pjfsilva's AJAX-loading related comments).
