I have been noticing that content-rich and feature-rich web pages arrive
piecemeal to my browser and often take a long time (5-30 seconds) to
finish arriving completely. This seems to have gotten worse during the
last few years, as portal pages are growing ever more elaborate.
For instance, I just timed how long, after I type ibm.com into my
address bar and hit enter, until all the whiz-bangs finish arriving: 12
seconds. Sun.com: 26 seconds. Dowjones.com: 23 seconds.
WashingtonPost.com: 12 seconds.
To time this, I watch the status bar in the bottom of the browser
window, and wait for "Done".
I am guessing that the bottleneck is not in my connection to the
Internet, since I download through Sprint residential ADSL at around 300
Kbps, but rather the bottleneck is in the application server. The
server just takes that long to fetch or create and then send dozens of
files or objects, I guess. Although perhaps the ADSL's 300 Kbps is a
seconds-long limit for some larger pictures or flash animations. I
suppose useful comparisons could be made in offices with faster connections.
If the bottleneck is indeed all the computing done in the web server and
beyond, are there indications that someone cares seriously about this?
It seems to me that it could be sped up if it becomes praiseworthy for
programmers to save cycles, once again.
Comments?
