Last year in my post “Microsoft the new #1 web server?” I described the changes in web server market shares according to Netcraft. However, these statistics might give a somewhat wrong overall picture as Netcraft apparently counts every virtual host as one server.

If you look at the most recent web server survey from Security Space you will notice that the changes are far from dramatic (at least from Apache’s point of view). Furthermore it also looks like Netcraft are adjusting/reversing the trend displayed last year.

Historical market share - Across all domains

Netcraft

Security Space

While Apache continues to grow Microsoft seams to go the other way. The interesting part is that “other” web servers are continuously gaining more and more market shares. This I believe is a result of social networking sites and blogs. Wordpress.com for one are running on LiteSpeed, and YouTube on Lighttpd due to its great ability/speed serving static content.

It will be interesting to see how things changes in the future, and if LiteSpeed was available on Windows I would definitely give it a try.

Do you know of any other reliable web server surveys or have a web server you would like to mention, then please leave a comment below.
