Are Disqus, Tweetup, Facebook and Twitter Slogging Your Blog?
- cheald 16y agoYes, absolutely. Facebook is the worst offender by far, here - it loads separate resources (CSS, extra JS, different URI but equal in content) for every button on the page. Blocking it results in a startling faster web browsing experience. I don't have benchmarks on hand, but if you use Chrome's profiler and inspect heap sizes in pages like Techcrunch and Mashable, the heap size when you block Facebook assets is ~50% of what it is otherwise. It's pretty bad how badly those widgets slaughter page performance.
