About this blog…

I am employed by Netnod as head of engineering, research and development and am among other things chair of the Security and Stability Advisory Committee at ICANN. You can find CV and photos of me at this page.

As I wear so many hats, I find it being necessary to somewhere express my personal view on things. This is the location where that happens. Postings on this blog, or at Facebook, Twitter etc, falls under this policy.

The views expressed on this post are mine and do not necessarily reflect the views of Netnod or any other of the organisations I have connections to.

Optimization of web pages?

An article in Ny Teknik in Sweden discuss search engine optimization. Some good ideas, but of course the most important thing is that articles discuss the phenomena. Are the organisations that optimize the pages in combat with Google? Or are they only fighting each other?

What I also would like Ny Teknik to look more closely at are other ways of optimizing. Optimizing the pages themselves. By for example looking at their own webpage. Just look at how many different domain names and servers the content is stored on. Each lookup in DNS takes time, and each new TCP connection for HTTP takes time. And what is worse, Ny Teknik can not themselves control the experience of the end user. Specifically when external sites are in such bad shape. Have a look at the diagram below and see how slow a specific server is from which Ny Teknik incorporate content.


adserver.adtech.de is slowing down the Ny Teknik website considerably
