So the question (for me) of size/speed comes down to: is it faster/better to build my own jQuery UI js file with selected components or to use the full file from Google's CDN?
The former option has the benefit of being smaller, while the latter has the benefit of being hosted by Google's fast servers and there's a decent probability the client already has it cached.
when using jquery and other google hosted frameworks, i tend to use them from google CDN because a lot of the time not only is it faster, but it tends to be faster for traffic from all over the place. i have a site hosted in hong kong and most of the traffic is from japan, africa, and south america, so obviously the performance will differ for different users. but when i use jquery from google CDN, the performance tends to be similar across users.
