How popular is Varnish? (Plus words from its creator)

Varnish HTTP acceleratorA really effective way to speed up a website is to add some form of caching layer in front of it. If your web server doesn’t have to keep generating the same web pages over and over, odds are things will be a lot faster for your site visitors. This is where Varnish comes in.

According to our research, 5.2% of the world’s top 10,000 websites are currently using Varnish, a popular open source HTTP accelerator (also called a reverse proxy) that acts as a caching layer between a website and its visitors.

Netcraft web server stats 2003-2012 in one chart

web server surveyToday Netcraft released its web server survey for July 2012, and we know many of you hurried to read how things have developed since last month (as did we).

What we’ve done is collect Netcraft’s data going back to 2003 and put that in one spreadsheet, which makes it easier to see how things have developed over the last 9 years or so. You can see the rise of NGINX, the fall of a few servers, as well as the continued domination of Apache.

75% of top 10k websites served by open source software

open source web servers

We have analyzed the top 10,000 websites in the world to find out what web server software they are running. Here is what we found out.

First of all, it is clear that open source software rules the roster. This largely thanks to two massively popular open source projects: The Apache web server, and the nginx web server. Together they account for at least 61% of the top 10k sites.

10 questions about web performance

In our continuing series of interviews about web performance, we’re now joined by Yannick Kunegel, Manager, Systems Engineering – Eastern Europe, Middle East, and Africa at Citrix Systems.

Citrix may not be the company that comes first to your mind when thinking about web performance or web companies. But if you look at its wide range of products and services, you’ll see that they do care very deeply about the web and how fast web services are for users.

10 questions about web performance

After our last interview with a representative of the Apache HTTP Server Project, we didn’t expect to hear so soon again from the leader in web server software.

But we now have the great privilege to present an interview about web performance with Sander Temme, member of the Project Management Committee member and contributor to the Apache HTTP Server project.

This is a part of our continuing series of interviews about web performance.

How the Apache HTTP web server stays secure (interview)

The Apache HTTP Server is the most common web server software in the world, by far. According to one recent survey, over 420 million web sites run Apache HTTP. With such amazing numbers it’s obvious that we’re curious to find out more about Apache.

So it was with great gusto that we sat down with the former Vice President of the all-volunteer Apache HTTP Server Project to talk about a wide range of topics. We grilled him on how the team works internally with keeping Apache HTTP Server secure, if they look at market share numbers, and whether or not open source software is more secure than closed source software.

It was quite an eye opening experience in many ways. Read on to find out why.

No news is good news for the Super Bowl website

The New England Patriots held what seemed to be a commanding lead (17-15) with five minutes left of Super Bowl XLVI last night. But the New York Giants came back and managed to win with 21-17.

As exciting as the game sounds, we missed the whole thing, instead spending our time watching the website.

It turned out to be a rather dull thing to do because the site held up well and there was no downtime at all. The response time also didn’t give away anything significant in terms of online Super Bowl traffic.

Forecasting NGINX and IIS web server software growth in 2012

Last week we published an article declaring that NGINX had become the second most used web server software in the world, thereby overtaking Microsoft Internet Information Server (IIS).

In that article, based on figures from Netcraft’s Web Server Survey, we looked at the data for “active sites.” NGINX had in that category pulled ahead of IIS for the first time, even though it was by a slim margin. NGINX accounted for 22,221,514 servers and IIS accounted for 22,142,114.

As we noted then, if you instead look at Netcraft’s “Market Share for Top Servers Across All Domains,” NGINX is still behind IIS. The margin is substantial but closing. We stated that NGINX might take the number two spot even in that category this year.

Now, let’s find out if that can happen and if so, when.

Apache is still the undisputed king of web server software but according to the latest Netcraft Web Server Survey from November 2011, NGINX usage has grown almost 300% over the last year.

In real numbers NGINX increased from about 15 million sites a year ago to 43 million in November 2011. That’s a faster growth than any other web server software tracked by Netcraft.

Since we’re big fans of NGINX at Pingdom, we wanted to try to understand this tremendous growth, so we put some questions to Andrew Alexeev (Q&A further down). Andrew looks after Business Development and Marketing for NGINX Inc., the company formed in October this year, backed by $3 million in venture funding, with the intent to expand the open source NGINX project and explore commercial opportunities.

Microsoft IISApache has been the most widely used web server on the Internet since the early days of the Web. It still is. The second-most popular web server has been, and still is, Microsoft’s Internet Information Server, IIS. But Microsoft’s web server is now losing ground.

It wasn’t always like this. For quite some time, IIS was gaining ground on Apache, but the tide changed in 2007. Since then Apache has recovered much of its previous dominance, reaching a 65% market share, while the market share for IIS has dwindled below 16%, less than half of what it used to be. That’s a pretty steep drop, bringing the IIS market share back to what it was in 1997, 14 years ago.
