Using latest version of UI (1.5b2), I have seen a big performance problem with the slider: moving it feels really sluggish.
I have profiled the script and most of the time is spent in the css function. It seems this is called by handleSize for each mouse move (it calls outerWidth/outerHeight).
I don't know all the corner cases, but this width is fixed for me so it's totally useless to calculate it each time. This should be cached during initialization, if possible.
Patch fixing my problem
I attached a patch that solved the problem for me.
Fixed in r5400.
