Doing Web Performance can be so easy, really! I was asked to do a performance analysis of a new website and one of the things I didn’t like was the fact that the footer contained social media sharing buttons using the ShareThis widget. I’m not a fan of sharing widgets in general, as they tend to slow webpage loading and rendering down and as they almost invariably come with “3rd party tracking” for behavioral marketing purposes.
it’s probably far from perfect and it sure isn’t pretty, but it works and the webpagetest.org-results tell it all.
|ShareThis||AddThis||Lockerz/ AddToAny||inline JS (“lyteShare”)|
|Full Download size||70 KB||384 KB||111 KB||7 KB|
|Test Report||sharethis result||addthis result||lockerz/ addtoany result||lyteshare result|
|3rd party tracking?||yes||yes||yes||no|
Conclusion: if performance is of any importance for your website (and it should be), you really have to avoid using 3rd party widgetery!
