Performance Testing Insights: Part I

Performance Testing Insights Featured Image

Performance Testing can be viewed as the systematic process of collecting and monitoring the results of system usage, then analyzing them to aid system improvement towards desired results. As part of the performance testing process, the tester needs to gather statistical information, examine server logs and system state histories, determine the system’s performance under natural and artificial conditions and alter system modes of operation.

Infographic: Web Performance Impacts Conversion Rates

There are many companies that design or re-design websites with the goal of increasing conversion rates. What do we mean by conversion rates?

However, we at LoadStorm want to draw more attention to the role that web performance plays in conversions. Many studies have conclusively shown […]

Does Adblock improve your load time? An essential rule is to have ad banners displayed after the main content is displayed. In terms of perception, users wont notice the banner until they find the content they’re looking for on the page. While your web page will most likely download less data, your perception of speed isn’t likely to fluctuate drastically due to the adblock extension. Perhaps testing this would be an interesting experiment! How does adblock work? Adblock takes the div of the ad and gives it a height of 0. You can test this by putting a mini ad […]

This gave them the power to set the standard. Unfortunately, the standard was set all the way down to Satan’s feet. Because there wasn’t any competition at the time, the standard didn’t matter. Web developers had to make their websites compatible with IE. It was never the other way around. The lack of debugging tools, performance optimizations, and upgrades were little to none. IE 6 was released in 2000. For five […]

Performance Testing Interview with Phillip Odom

Phillip Odom’s background is in Electrical Engineering/Computer Engineering. Phillip grew up in Nashville, TN in the late 1970’s and 1980’s with access to “home computers” like the Tandy TRS-80, the Commodore 64, the Apple II, the Amiga, etc. So his childhood was spent making these quirky and somewhat crude machines do things, sometimes anything.
