How Strangeloop helps you control rogue site content: Third-party timing and SLAs

28 May 2012

Why run up a $100K/month CDN tab if you're going to implement a single line of JavaScript that could take down your site? There's simply no rationale behind allowing this to happen, especially given the costs of using a content delivery network.

Here's how Strangeloop helps you regain control over out-of-control third-party scripts...

The problem: Poorly optimized third-party content often blocks page rendering, and seriously hinders web performance.

Poorly optimized script for advertisements, social media widgets, or analytics support can block a page from rendering, sometimes adding precious seconds to load times. (Parsing JavaScript can take up to 100 milliseconds per KB of code on some mobile devices. Those milliseconds can add up quickly!)

The question is, since these slow-loading scripts are controlled by third parties, how can site owners prevent them from adding critical seconds to their page load times?

Our solution: Give site owners control over how, when, and if third-party scripts are allowed to load.

We've developed a feature in both our Site Optimizer and Mobile Optimizer solutions that gives site owners yet another valuable tool for controlling their web performance.

This feature – called Third-Party Timing and SLAs – allows site owners to create automated service level agreements (SLAs) that allot a maximum wait time for each third-party script on a page. If the script has not loaded within this time frame, it's deferred until after the page renders, or else it is cancelled altogether. This eliminates delays and page timeouts caused by poorly optimized third-party scripts.

How it works

Many script libraries aren't needed until after a page has finished rendering. Downloading and parsing these scripts can safely be deferred until after the onload event. Our development team has identified a number of script libraries that can be deferred safely until after the rest of the page has rendered.

This feature is fully customizable. You have complete control over the settings for each third-party script -- from the amount of time to allow each individual script to load to the decision as to whether or not to cancel the script completely if it fails to load within the designated time. Once you've set your third-party controls, our automated solutions manage your scripts in real time. You can adjust your settings at any time.

Whether cancelled or deferred, Third-Party Timing and SLAs prevents unoptimized scripts from needlessly holding up the initial rendering of important page elements.


Strangeloop makes Network World's 2012 Fave Raves list

17 April 2012

AutoAnything CTO Parag Patel explains to the editors of Network World why he nominated the Strangeloop Site Optimizer as his favorite IT product:

"Website acceleration became a priority for us in the fall of 2009, as we were gearing up for Black Friday. Site Optimizer was easy to implement and delivered immediate results. After being deployed, Site Optimizer instantly cut our page load times in half.

"We conducted a 50/50 test of our site's traffic and learned that making our pages faster had a major impact on key metrics: On the accelerated site, conversions increased by 9%, order size by 11%, and sales by 12%. These improvements are extremely significant on an annual basis."

Each year, Network World asks IT pros what they love -- which tech products make their lives easier, provide stellar security and compliance, and help keep end users happy and productive. The top 20 are corralled into the Fave Raves roundup. This year, Strangeloop is joined by companies like F5, Meraki, and Compuware Gomez.

New case study: accelerates load times by up to 45% across all browsers

13 April 2012

The team at had a clear understanding of their performance challenges: serving eight versions of each content-rich page across the country to customers using older browsers. They also knew they had their work cut out for them when it came to finding a solution that would take them to their goal of delivering sub-3-second pages to their customers.

"Not only do we serve more than 13,000 product pages in a year, we also have to serve eight different versions of each page, due to the complex legal stipulations for shipping wine to various states," explains CTO Geoffrey Smalling. "When a visitor comes to our site and clicks on a product link, our site has to scan the legal requirements for that person’s state, dig up the content that correlates to their state’s shipping laws, then serve a fully tailored page -- all in less than three seconds." was also constrained by the fact that many of its visitors were using dated browsers. "It took us a while to pinpoint this issue, but we eventually realized that a number of our highest-spending customers work in the financial services sector, and they were placing orders from work. Many of these customers were restricted to using Internet Explorer 6 and 7, which our site was not optimized for. As a result, these people were getting really sluggish pages."

This problem was compounded by the fact that's datacenter is housed on the west coast, while a significant portion of its customer base lives on the east coast. Moving that payload across the country resulted in pages that loaded, at best, in about four seconds.

Four-second page load: Not fast enough

While some companies would consider four seconds a performance success, knew this wasn’t a laurel to rest upon. Their goal was under three seconds.

"A four-second download was acceptable at one time, but today it’s far too slow, given advancements in computer technology and growing consumer expectations," says Mr. Smalling. "Getting closer to two seconds was an ambitious goal, but we had to reach it or lose potential customers, especially first-time visitors."

Why Strangeloop?

"When we started our search for a performance solution, Strangeloop immediately stood out from the crowd," says Mr. Smalling. "Being able to optimize for all browsers and operating systems, consistently and securely, is an impressive claim. We knew that if a single product could do all that for us at an affordable cost, that would be a fantastic achievement." completed their Strangeloop Site Optimizer implementation just in time for the 2010 holiday shopping season, and they saw immediate dramatic improvement in all the metrics they cared about:

  • Pages load up to 45% faster across all browsers
  • Customizes optimization rules for their highly regulated business
  • Mitigates the impact of ever-growing pages
  • Complements other performance solutions (DSA and in-house performance engineering)

"Site Optimizer does exactly what it says it does," says Mr. Smalling. "It optimizes for every single browser and operating system. It's a great feeling to invest in a solution that actually delivers on its promise."

19 Things You Can Do to Make Your Site Faster for Mobile Users [WHITEPAPER]

7 March 2012

The launch of the new iPad is an excellent reminder that the mobile web -- once a fringe concern for site owners -- is crowding onto the center stage.

But with the mobile web comes a whole new set of challenges for site owners who care about delivering a speedy experience to their visitors: spotty (or throttled) networks, lower bandwidth, higher latency, smaller memories, and lower processing power.

While the new iPad boasts a more powerful processor than its predecessors, this only slightly mitigates these challenges. A further challenge: iPad users expect sites to perform as fast on their tablets as they do on their desktops. 

Our recent whitepaper -- Mobile Site Optimization: 19 things you can do to make your site faster for mobile users -- summarizes the case for mobile optimization, describes the unique performance challenges posed by mobile devices, and provides an overview of strategies and tactics you can use to speed up your site for mobile users.

In this whitepaper, you'll learn why and how to:

  • Consolidate resources
  • Use browser caching and localStorage
  • Embed resources in HTML for first-time use
  • Use HTML5 server-sent events
  • Eliminate redirects
  • Compress and minify page resources
  • Resize images
  • Simplify pages with HTML5 and CSS 3.0
  • Use idle time to preload resources
  • Defer loading and executing non-essential scripts
  • Adapt to the type of network connection
  • Replace click events with touch events
  • Support the SPDY protocol
  • And several more mobile-specific performance techniques

In a recent interview, Strangeloop customer told Retail Touch Points why they chose us to accelerate their premiere e-commerce site:

"A four-second download once was acceptable but today is far too slow, given advancements in computer technology and growing consumer expectations," stated Geoffrey Smalling, CTO of "Two seconds was an ambitious goal but we had to reach it or lose potential customers, especially first-time visitors."

Mr. Smalling talked about the challenges of optimizing content-rich pages for every browser type, the complexity of optimizing location-sensitive pages for customers around the world, why the pursuit of high-performing web pages is a neverending task, and how the Strangeloop Site Optimizer addresses all of these challenges. 

"It was an engineering challenge for Strangeloop to develop optimizations based on our unique, regulated business," said Mr. Smalling. "Strangeloop best handled enterprise scale via appliance or cloud and has an aggressive plan for further product development to keep us at the front edge of acceleration."

"The promise of a front-end optimization tool like the one we selected from Strangeloop Networks is that we don’t have to think about it ― the optimization is done for us. That promise has included a 45% improvement in speed on our New York homepage, 39% on Virginia’s and 35% on the Los Angeles page."

Case study: Slow shopping cart pages kill conversions. How optimizing just one page got a 66% conversion lift.

5 December 2011

In this guest post for the marketing blog Unbounce, Strangeloop president Joshua Bixby explains why every page of an entire online transaction needs to be as fast as possible. 

  • Only 3 out of 10 shopping carts make it through the checkout process.
  • The total cost of abandoned shopping carts has been estimated at over $18 billion a year.
  • 1 out of 5 customers will abandon their shopping cart if pages are too slow. That's more than $3 billion in lost sales due to poor performance.

To illustrate first hand the impact of slow pages on the checkout process and conversions, Joshua walks through a real-world case study with a Strangeloop customer who wanted to experiment with the impact of page slowdown on a 5-step transaction. We did a split test in which we divided traffic into three groups and delivered different load times to each.

What we found: Just a single slow page in a 5-page process significantly hurt conversions. Fixing that page resulted in a 66% conversion gain.

How the Strangeloop Site Optimizer works [VIDEO]

29 November 2011

Front-end optimization explained: find out how our Site Optimizer works in just 3 minutes!

While our Site Optimizer product and service aren't new, this video is. We were challenged (in a good way) to convey a lot of information in a very short window. At the end of the day, our goal was to give a high-level overview of the performance challenge, then highlight a few of the optimization treatments we offer via Site Optimizer -- from fundamental best practices such as consolidation through to advanced techniques like deferral and headstart.

Most important, we wanted to illustrate a couple of things that differentiate Site Optimizer from other front-end solutions:

First, its ability to look at the big picture and analyze all of a site's traffic -- its millions of visitor paths -- and then use this information to make sophisticated, on-the-fly decisions about optimizing a user's entire journey through the site.

And second, the fact that Site Optimizer takes everything it learns about a visitor and applies this to that visitor's next session on your site, making their experience even faster and more seamless. This is a key feature, because repeat users are the backbone of your organization.

We hope you enjoy this insight into our product. If you have any questions, we'd love to hear them.
