It causes a memory leak if you don't put the element(s) back in the document somewhere. jQuery will keep all the data (as in element.data() and references to event handlers) in memory when you use .detach.

That is the purpose of .detach: to not clean up because you are promising to put the elements back into the page soon. If you were not going to put them back, you would use .remove and that would clean up the data.

It is not about performance.
