title: jQuery 1.3 vs 1.4 (Performance)
body: <p>jQuery 1.4 released recently and the new website shows some performance charts where 1.4 is clearly better, but has someone already done an analysis of overall performance improvement of 1.4 vs 1.3? If not, how do I profile both on my sites/pages, are there any tools?</p>
  
  <p>Can't wait to find out how fast is 1.4 compared to the previous version.</p>
  
  <p><strong>Edit</strong>: A blogger did some <a href="http://st-on-it.blogspot.com/2010/01/so-is-really-jquery-14-30000-times.html" rel="nofollow noreferrer">tests</a> and found that its about 30% faster in FF but slower (compared to 1.3) in Safari. Hmm...</p>
