You may speed your code up ba choosing the selector. Usually just searching
for the id ahould be the fastest: $('#myid'). Number Two is searching for the
tag type: $('li'). Searching for classes is rather slow: $('.myclass').
If your page contains many elements, then using a context might speed up the
search for classes: $('.myclass',$('#commonAncestor')[0]).

You can try and cache results, speedup loops in callbacks, etc. There are many
possible ways to improve JS-code, but without any code I guess noone can
really help.
I do think that there are some spots in jQuery where the performance could be
improved. We have that discussion here once in a while. It basically comes
out to be a tradeof between readability and speed.
