This Week in Client-Side Performance

website-performance-weekly-monitorusIt’s Monday again and it’s time for our “Website  performance” weekly feature on the Monitor.Us blog. Each week we present you handpicked links on different aspects of website performance. This issue of our weekly mostly covers topics related to JavaScript Performance issues, however not limiting by just that.

Vote Now for Your Favorite Client-side Web Performance Tips

The tips were taken from many, many web pages. In most cases, they are believed to be true, but in general they remain mostly untested.Some tips are very effective. Others, though valid, have minimal impact. Others are just plain wrong. How can we tell what matters and what doesn’t? The answer, of course, is to do our own testing on our own production machine(s), but do we really have time to test hundreds of tips? I think not.We can help each other prioritize these tips. I’m asking each of you to vote for the tips that your experience has proven to be particularly effective. At the same time, vote against the ones you found to be ineffective. Together we can narrow the list for all of us.
Will you help?
Today’s list covers client-side tips, specifically- rendering and loading. Server-side and other tips are in later articles. Read more…

Compiling JavaScript for performance

Javascript performance tipsAs the reader already knows, computers don’t speak JavaScript. They speak their own language (machine code). Sadly, there is not just one machine language; there are several, and they are subject to change.In order to run a JavaScript program, the program must be translated into the client machine’s machine code. No matter how much we optimize the translation process, if it happens while the end-user is sitting at the machine waiting for a web page, then we have a performance issue. Ideally, the translation process should occur before the user requests the page.Today’s article discusses some of the performance issues involved in translating JavaScript to machine code.

When & Where

Interpreting and compiling are the same thing. The only difference is when they happen. Compiling happens before the program is loaded and executed. Interpreting happens on-the-fly, line-by-line while the program is executing. If an interpreted program seems slow, the translation process is partly to blame. However, if a program is compiled before the web page is requested, the translation process cannot be blamed. Read more…

Top 10 Javascript Productivity tools

top 10 javascript tuning toolsJavaScript tuning tools help to reduce the amount of time required to find leaks, tweak performance and monitor Java Virtual Machines. Developers who want to decrease their time troubleshooting can benefit from the advanced heuristics and simple graphical interfaces that display essential data. Tools greatly help to reduce the amount of time manually searching through code to find extra characters and inefficient coding.

1) Firebug
