The Facebook engineering blog often presents interesting findings about the nuts and bolts of Facebook and the technical side of running that enormous service. The latest post is about Facebook’s experimentation on how site speed affects the behavior of its users, called “Every Millisecond Counts”.
One thing that struck us as extremely interesting was the following findings about site speed.
Are you a programmer? Want to do something for the environment and even make the world a better place? Then start optimizing your code!
It seems like today the solution to most software performance issues is to throw more hardware at the problem instead of making the software run faster on existing hardware. Doing more with less is a forgotten mantra, and Wirth’s Law continues to ring true:
Software is getting slower more rapidly than hardware becomes faster.
This week Google launched a new Web community on code.google.com/speed. The goal is to help Web developers speed up their Web applications, but the long-term goal is even more ambitious; to work together to make the Web as a whole a lot faster.
Here’s some interesting news for all you webmasters and web developers out there. Google has just introduced a tool they call Page Speed that tests a web page based on a set of rules and best practices for fast-loading websites. It then gives you advice on what you can improve to make your website faster. It works as an add-on to Firefox and needs the Firebug extension to work.
Aside from uptime, website performance is something we talk a lot about here at Pingdom. There are lots of ways to improve the speed of your website, but this post will focus on ways to optimize the size and number of files your website uses, both being important factors affecting the load time.
The files we are talking about are of course the files that are delivered to a visitor when they load your website, such as HTML, CSS, Javascript and most important in this case, images.
Since images usually make up most of the size of a website, we will focus the majority of this article on image optimization.
This report presents an analysis of 100 top blogs, picked from the Technorati top 100 list. For each of these blogs, the front page (homepage) has been analyzed to see how large its download size is and what contributes the most to this size.
We have chosen to not present the blogs individually in this report, but have instead focused on them as a group to get more general data.
Steve Souders, the creator of YSlow and the author of the book High Performance Web Sites, is one of the most respected experts on website performance in the world. We here at Pingdom are big fans of his work, and decided to probe his mind about the excellent YSlow Firefox add-on for evaluating website performance [...]
On June 23-24, O’Reilly held the 2008 edition of Velocity, a conference focused on web performance and operations. Unfortunately no one from Pingdom was able to attend (much to our great dismay considering the subject matter), but luckily for us the slides for a lot of the presentations have been made public.
We have scoured the [...]
We have used Yslow, Yahoo’s performance plugin to Firefox, to analyze the performance of the top 100 websites in the US according to Alexa. The results were both surprising and interesting.
Yslow will rank websites using 13 different criteria that are known to affect website performance, such as the number of HTTP request, how scripts and [...]
