Statistics about average webpage size

A post from April 2008, but still very interesting. Some good indications if you would like to compare your own web-production with some average figures.

Average webpage size triples since 2003

webpage size

From 2003 to 2008 the average web page grew from 93.7K to over 312K, some 233%.

During the same five-year period, the number of objects in the average web page nearly doubled from 25.7 to 49.9 objects per page.

Longer term statistics show that since 1995 the size of the average web page has increased by 22 times, and the number of objects per page has grown by 21.7 times.

Response time trends

For broadband users the average download time of the Keynote Business 40 Internet Performance Index (KB40) has decreased from 2.8 to 2.33 seconds from Feb. 2006 to Feb. 2008

So the increase in the average speed of broadband has more than kept pace with the increase in the size and complexity of the average web page. That is one reason why broadband users expect faster response times. Yet narrowband users have experienced slower response times as web page size has increased.

Use of Javascript

In the 2007 survey, 84.8% of web pages used the script element.

The average size of external scripts was 8,845 bytes uncompressed, and 6,302 bytes compressed. Total script size was 68,812 bytes uncompressed and 49,738 bytes compressed.

The average number of external scripts was 7, where 6 of which were unique.

Use of CSS

In the 2007 survey, 82.4% used the link tag, and 54.5% used the style tag (with an average of 2.27 style tags used internally).

The average size of external style sheets was 6,575 bytes, and 4,457 bytes compressed. The total average style size was 15,175 bytes uncompressed, and 10,347 bytes compressed.

Use of images

Images were used in 91.6% of web pages in the 2007 survey.

Quite useful!

Impressive figures from the Linux kernel development

via 451 CAOS Theory

Great post about some impressive figures from the Linux kernel development.

There have been almost 10,000 patches in each recent quarterly Linux kernel release.
Releases include work from ~1,000 developers and ~100 companies.
Since 2005, Linux has had more than 3,600 individual developers and more than 250 companies contributing to the kernel.
The individual development community has tripled in the last three years.
The top 10 developers have contributed 15% of changes, and the top 30 developers have contributed 30% of changes to the kernel.
Linus Torvalds is 27th on the list of contributors with most changes over the last few years. He has 495 to his name.
More than 11,500 or 14% of kernel changes have come from developers with no commercial entity backing their Linux development.
Another 13% of changes come from developers with ‘unknown’ commercial affiliation.
When we get to actual companies, Red Hat leads with 9,351 kernel changes, or 11.2%. Next is Novell with 8.9%, IBM with 8.3% and Intel with 4.1% of kernel changes.
More than 70% of all kernel development is demonstrably done by developers who are being paid for their work.
From the 2.6.11 kernel to the 2.6.24 release (1,140 days), there were an average of 2.8 accepted patches applied to the Linux kernel tree per hour.
An average of more than 3,600 lines of code is added to the Linux kernel tree every day.
Since 2005, the kernel has grown at a steady rate of 10% per year.

Gosh, if this is not showing the incredible health and dynamism of the Linux community!

Blog statistics 2007

As usual, I would like to give you transparently some information about what was going on there, on this blog, in 2007. And since the start of this blog in March 2004.
