Two days before the Super Bowl people are not only betting on the winner, but also on the best commercial. Will the millions of dollars spent really pay off for the advertisers? We took a closer look at the Super Bowl Ad landing pages for these Super Bowl Ads. Our synthetic monitoring showed huge differences ranking from 1.4 to 10s+ load time. If these pages are already slow prior to the big day, we wonder how they will do on Sunday and if there is anything that can be done to speed things up.
With this blog we hope to give a wake-up signal to some of these companies. They need to take another look into their current deployment because we see a lot of web performance mistakes all over the place like:
- CDN Configuration Problems
- NOT optimized for Mobile
- NOT following Best Practices such as Spriting.
For Business Owners: Talk with your IT Teams and make sure they have the time and resources to analyze and do last minute fixes - otherwise it is possible that even with the funniest ad, you won't be able to convert viewers into customers because your website may crash or be slow. You can check out how fast your page is in the moment: Run an Instant Test with Compuware APM/Gomez.
For the DevOps and Web Architect Team: Run a quick sanity check with tools such as Compuware APM/dynaTrace AJAX Edition, PageSpeed, FireBug, ... and follow the best practices we have been talking about in the recent years.
CDN Configuration Problems
One of the advertisers landing page loads 248 images on that page. Most of these images are served from the home domain (e.g., www.company.com). Others are severed from Amazon's CDN. What's interesting is that on this page, 46 of these image requests result in an HTTP 403. This is a lot of time wasted by the browser and impacts the end user because he has to wait longer for the full page to load:
CDN Configuration problems lead to HTTP 403s and impact total page load time
Next Steps: Figure out if these image URLs are valid and really needed for the landing page. If so - check the CDN configuration. If they are not needed, they probably got onto the page by accident. Make sure to remove them from the HTML document so that they don't impact page load time.
Not Optimized for Mobile
How large do you want a mobile web site to be? 100k, 1MB, 10MB? Even though many of us now have LTE or 3G, downloading large web sites on a mobile device will always impact user experience. One of the mobile versions of the landing pages that I analyzed had 20MB in unzipped content and took about 15s to load. I used a Wi-Fi connection for this test. Here are the other Key Performance Indicators showing that this site is definitely NOT Optimized for Mobile:
The mobile version of the web site was very large (20MB) and had too many resources (434) until it was fully loaded
Next Steps: I would ask the question: why it is necessary to download all these images on the initial landing page when only a handful of them are shown anyway? Loading images of a picture gallery in advance will speed up scrolling through the gallery, but it will also impact the first impression of that page. This will make end users wonder how much data they just downloaded to access a "mobile" web site.
Business Folks: Don't waste your money - give IT more time to focus on web performance
After so many years of Web Performance Optimization Best Practices it still interesting to see "performance landmines" like the ones highlighted here. And - these are just a few of many that we found. If you want to learn more about what it takes to prevent these problems right from the start then check out some of our other blogs on Best Practices for DevOps and Avoiding the Classical Business War Room Scenario.

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...

No matter how well-built your applications are, countless issues can cause performance problems, putting the platforms they are running on under scrutiny. If you've moved to Node.js to power your applications, you may be at risk of these issues calling your choice into question. How do you identify vulnerabilities and mitigate risk to take the focus off troubleshooting the technology and back where it belongs, on innovation? There is no doubt that Node.js is one of today's leading platforms of ...

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor – all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organization...

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.
They are not.
One is about the application. The other, the network. T...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...
