How Busy is the CDN?

Posted November 25, 2013 by Esteban Martinez 0

In our previous post about helping the Delivergood Magento store by enabling a Cloudfront Content Delivery Network (CDN) distribution, we saw the benefits that a CDN could provide for their store’s scalability. Let’s go into detail about how you might shape your distribution by asking some questions. Do you want the CDN distribution to take almost all the work off of your main server or only some of it? How busy do you want to keep the CDN distribution? All of these questions determine how much time you will put in obtaining the most out of your Cloudfront distribution. For […]

What’s Cached in W3 Total Cache?

Posted October 9, 2013 by Dan Green 0

There are four caching options within W3 Total Cache: Object caching, Page caching, Database caching, and Browser caching. What’s the difference between all these options? What do they all mean? Why does it matter? All were questions we had when we installed the plugin, so we thought we’d share the answers we found with you. What is caching, again? Caching is the act of storing data in such a way that future accesses to that data are faster. Typically caching involves moving data from a slow location to a fast one. The hard drive has hundreds of times more storage […]

Site Scalability with a Content Delivery Network

Posted October 7, 2013 by Esteban Martinez 0

Sometimes you put so much effort into making your website scalable, efficient and optimized that you start seeing diminishing returns. Sometimes you need to literally think outside the box, or in this case, the server. A Content Delivery Network (CDN) would get us past these limits by putting less pressure on the one web server. If you don’t know much about a CDN, take a look at Dan’s blog post. The Web Performance Lab recently partnered up with Delivergood (a charity supply distributor) to accept the challenge of getting their Magento web store to handle up to 2,000 real-time users. […]

WebPerfLab: Interactive Google Map is 300% Slower vs Still Image

Web Performance Lab - Featured Image - Google Map vs Still Image

Posted September 23, 2013 by Michael Dunagan 0

Recently I compared performance tests of our Contact-Us page for embedding an interactive Google map versus using a simple JPEG screenshot with a hyperlink to the full Google map. What I found was that the interactive Google map on average made our Contact-Us page: 3x Slower Page Load Time 7x Larger (cumulative file sizes) 5x more HTTP requests To start I went to webpagetest.org and ran 11 tests from Dulles, VA on the Chrome browser for a 5 Mbps connection targeting our Contact-Us page with the embedded Google map, and I got some rather slow results considering how many optimizations we had recently done […]

WordPress Performance Tuning: Page Caching, CDN, and JavaScript Files

Posted September 13, 2013 by Dan Green 0

We’ve run many tests on LoadStorm’s website and shared the results in different blog posts. These are the first set of experiments for our Web Performance Lab, and we hope you read them because the details can be very helpful to anyone learning about WordPress performance, web scalability and page speed. The results below are focused on page speed measurements – not scalability. We’ve tested several individual optimizations such as page caching and deferring JavaScript. What we haven’t looked at, though, is how well those optimizations work when they’re put together. As we’ve mentioned before, after testing these performance optimizations, […]

WebPerfLab – JavaScript Optimizations

Posted August 22, 2013 by Dan Green 0

Would you be surprised if we could DOUBLE THE SPEED of perceived page response by simple tweaking of script references? How about if we could make the browser work more efficiently to download more images in parallel, thereby reducing the page load time to about 3/4 of its original – would you find that exciting? If not, you’re not a performance geek, and you should be reading someone else’s blog. Since you are a perf geek, read on for the cool data. For our optimization experiments, we tested two changes concerning the usage of JavaScript in our WordPress site that […]

WebPerfLab: Benchmarking Challenges

Posted July 30, 2013 by Dan Green 0

Data is pretty much meaningless without something to compare it to. I could tell you that a certain individual weighs 246 pounds after dieting, but it makes more sense to also say that they weighed 310 pounds before they started. The effectiveness of the dieting plan can only be shown by comparing before and after. Similarly, in performing our optimization experiments, it just makes sense to gather some “before” data with which to compare our post-optimization speeds. Gathering our benchmark data isn’t quite as simple as putting our servers on a bathroom scale. There are many distinct measures of performance, […]

Responsive Design Performance: Benefits & Challenges

Posted July 9, 2013 by Arwen Price 0

If you haven’t heard of “Responsive Design” before this point, I want you to do something for me. If you’re reading this on a desktop, please reach over to the side of your browser window and resize it. Scale the width to about half. Then scale it down further. Keep going until you can’t scale it down any more. Don’t just read on ahead to see where this is going. Seriously, do it right now. Pretty cool, huh? Since I’m assuming you’re reading this on loadstorm.com, you may have noticed something interesting happen to the page elements as you scaled. […]
