How Fast is Your Website? Increase Website Speed Instantly

, 15 Apr 2010
The most popular websites on the web today load quickly; visitors don’t like to wait. Slow websites hurt brands, frustrate visitors, and cost more in terms of visitor productivity and data-transfer. Increasing the performance of your website is now not only easier, we've made it automatic.

Editorial Note

This article is in the Product Showcase section for our sponsors at CodeProject. These articles are intended to provide you with information on products and services that we consider useful and of value to developers.

Aptimize Website Accelerator

The world’s biggest companies trust Aptimize to accelerate their websites and intranets.

Aptimize Website Accelerator uses best practice techniques to optimize web pages in real time instantly accelerating your website or intranet with a simple software installation on the web server without the need to add extra hardware or make code changes.

Aptimize Website Accelerator is an ISAPI filter for Microsoft IIS, or a Daemon and module for Linux Apache; it automates performance tuning by dynamically optimizing web pages for high performance at runtime – just before a page is sent from web server to browser.

Aptimize reduces page load times by up to 75%.

Aptimize takes the industry from "here's what you need to fix" to 'fast by default'. This is the next step in performance tool development - automatically making any web page faster without the developer having to do any additional work.
Steve Souders, Web Performance Lead, Google

In a step to encourage faster loading websites, because visitors prefer them, Google recently made site speed a ranking factor in Google’s search algorithm. Fast websites will now be favored over slow websites in its search results.

Take the website speed test. We will send you a report showing the first view and repeat view page load time, the YSlow score for your website, and the speed improvements you will gain with Aptimize.
