It started with this letter of apology on the corporate site of jetblue.com which was quite impressive. Discarding the content I liked the design and the simplicity of the navigation.
Then I clicked to go to the homepage and noticed how my Firefox almost froze and started stuttering. Even though the homepage fits on one screen and hasn't got much information it took 11 seconds to download it completely! (apple.com takes 4 seconds, peterbe.com takes 2 seconds on this WiFi connection I'm at)
Here's the explaination why:
Documents (2 files) 30 kb Images (54 files) 114 kb Style Sheets (5 files) 25 kb Scripts (17 files) 165 kb Total (78 files) 333 kb
For that little page it takes 78 requests to be sent to get the whole thing. I don't care how fast those individual requests are because it's the total that counts. And unless you're on a supercomputer you'll definitely feel how slowly your web browser is piecing together those 54 images that it needs to download.
