This blog post is 5 years old! Most likely, its content is outdated. Especially if it's technical.
The number one rule in the general best practice of web performance is "Minimize HTTP Requests".
Yeah, it's more important than anything else.
So, I took the biggest offender from the collected sites Number of Domains and ran it through WebPageTest. The result is almost comical.
That's amazing! I'm not even sure I could achieve that even if I tried. It's almost like those sickeningly infested Internet Explorer toolbars that are often a joke.
Some numbers to blow your mind (on a DSL connection from San Jose, CA, USA)...
- Time to fully loaded: 85 seconds
- Bytes in: 9,851 KB
- Total requests: 1,390 (!!)
- SpeedIndex: 10028 (my own site's 950)
What's mindblowing about how bad this site is that even on the repeated view, where a browser cache is supposed to help a lot, is that it takes 30.6 seconds and still makes 347 requests. Just wow!
