So I was doing some experimenting with prototype and ajax and discovered  
something interesting. When I use the first ajax call the response from  
the server take 53ms. When I use the second on using the prototype  
functions the request from the server is over 200ms. My question is  
why, and can it be fixed?

Call server-side function

Update element

Thanks

You might find that the guys on the prototype-scriptaculous list are  
more clued up on this.
