Wanna better user experience for your web offerings? Razor Optimizer is one of our attempts in doing so. We are not quite there yet. Please take a look at below and click "Accept and Proceed" when you are ready to give it a try:

Welcome to Razor

This is pre-release software. The followings are the major known limitations for this pre-release:

1. Relative URL:
Your application page must only contain relative URLs, not absolute URLs. For example, if your page has <script src="http://a.com/b/a.js"></script>, Razor will not be able to process this file. However, if you change the declaration to a relative URL such as <script src="/b/a.js"></script>, Razor will be good;

2. Performance:
We have applied a lot of existing optimization techniques on Razor so far, such as caching, concatenation, compression, etc. But you can still see performance problems! Ironic? These performance problems serve as good examples showing the limitations of existing techniques. We will profile Razor using Razor itself. We think performance will get much better then!

Thank you for trying it out! Please share your thoughts!

Why Should I Care?

The Web has evolved, but the ways that we monitor, profile, analyze and optimize web experiences have not quite caught up yet.

Today's web applications are very different from those ten years ago. The front-end is gaining prominence comparing to web 1.0's back-end centricity. Today's applications use Ajax extensively for richer interactivity. Over the last ten years, the average web page size has increased 22 times, and the number of external objects per page has grown 21.7 times.

But the ways that we monitor, profile, analyze and optimize web applications have not quite caught up yet. Though the front end is where 80% or more of the end-user response time is spent, the ways that we monitor, profile, analyze and optimize user experience are still very backend-centric. Content delivery services, site monitoring, performance tuning and optimization techniques are still very much the way they were ten years ago. They are still very important, but the new landscape calls for some new thinking.

Razor represents such an attempt. Razor is still early and it still has many problems. Would it make a difference? Maybe yes, maybe no. Give it a try.
