Apps Eat More Bandwidth than Browsers

NetForecast sheds light on how apps and browsers consume bandwidth
Submitted by Sevcik and Wetzel on Mon, 01/23/12 - 9:43am.

As iPads, iPhones, Nooks, Kindles, and other mobile devices multiply like rabbits and join the established population of desktop and laptop computers, the nature of traffic to and from all device types is changing. The key reason for this change is that users are downloading more apps, which replace the browser for completing most tasks. Mobile device users generally rely more heavily on apps to do their bidding, while computer users continue to rely more on browsers.

Prepare Ye the Way of the Intercloud

Cloud federation will happen
Submitted by Sevcik and Wetzel on Mon, 01/09/12 - 5:39am.

The term Intercloud describes the future interconnectedness--or federation--of clouds, similar to the network of networks that is today's Internet. Like the electrical grid, in which a utility is shared based on supply and demand, the Intercloud will be a mesh of cloud computing resources owned by many, and interconnected and shared via open standards.

Energy Star Equivalent Needed for Application Bandwidth Consumption

It’s time to address content provider-generated bandwidth demand
Submitted by Sevcik and Wetzel on Mon, 12/05/11 - 11:13am.

The FCC (or someone) should implement an Energy Star equivalent for bandwidth consumption by Internet applications such as Google and Facebook to educate consumers about demand placed on their broadband connections by the prodigious growth in resource consumption by major websites, browsers, and behind-the-scenes services. The Internet is an economic ecosystem. It is impossible to promote its health by focusing solely on either the supply or the demand sides of the system. Until now, all eyes have been on the supply side but not the demand side.

Do Broadband Consumers Get the Bandwidth They Pay For?

NetForecast analysis shows that generally when you buy more bandwidth you get it
Submitted by Sevcik and Wetzel on Mon, 11/28/11 - 11:07am.

NetForecast examined the FCC's Internet connection performance data to determine if consumers are receiving the bandwidth they pay for. We found that the higher the bandwidth purchased, the better the chance that the bandwidth delivered meets or exceeds advertised levels. At lower service tiers, consumers generally receive less bandwidth capacity than advertised, while at higher tiers consumers tend to receive more than the advertised bandwidth capacity, except during peak usage periods

Laws of Internet Resource Supply and Demand

Payload consumes bandwidth and application turns consume latency
Submitted by Sevcik and Wetzel on Mon, 11/21/11 - 7:34am.

Like most systems, the Internet is subject to the laws of resource supply and demand. Demand for Internet resources that affect speed is most heavily influenced and driven by the way websites are designed and operated. The primary factors influencing the demand for resources that affect page load time are payload size and application turn count. Payload consumes bandwidth resources, and application turns consume latency.

No Matter What the FCC Says, Bandwidth Is Not Speed

FCC erroneously uses ‘bandwidth' and ‘speed' interchangeably
Submitted by Sevcik and Wetzel on Wed, 11/16/11 - 6:24am.

In its recently published Measuring Broadband America report, the FCC erroneously uses the terms 'bandwidth' and 'speed' interchangeably. The FCC should know better. ISPs claim to deliver high speeds if you buy their higher bandwidth services. This misleads consumers into assuming that a higher bandwidth connection will automatically deliver a faster user experience. In fact, bandwidth is but one of a half dozen factors that affect user response time (a.k.a. speed).

Assessment of FCC’s “Measuring Broadband America” Test Methodology

NetForecast suggests methodology improvements
Submitted by Sevcik and Wetzel on Mon, 11/14/11 - 11:18pm.

Based on NetForecast's analysis of the test methodology underlying the FCC's Measuring Broadband America report and our experience evaluating alternative consumer broadband performance measurement methodologies, we conclude that the SamKnows consumer premises measurement boxes used produce high-quality test results. That said, however, some of the test servers introduced data inconsistencies and errors, and the data analysis was insufficient transparent to fully validate the results.

FCC’s “Measuring Broadband America” Report Tells Only Half the Story

It’s time to look at demand for Internet bandwidth
Submitted by Sevcik and Wetzel on Mon, 11/14/11 - 7:27am.

The recently published FCC Measuring Broadband America report, which publicizes measurements of US ISPs' broadband performance, covers only half of the broadband performance equation--the supply half. NetForecast believes it is time for the FCC to expand its investigation to include the demand half of the equation--the prodigious growth in resource consumption by major websites, browsers, and behind-the-scenes services.

NetForecast Publishes APM Best Practices Benchmarking Report

Best practices lead to 75 percent better performance results
Submitted by Sevcik and Wetzel on Mon, 10/24/11 - 9:47am.

This week NetForecast publishes a free report detailing the findings of our recent APM best practices benchmarking survey. The results document how, compared to enterprises with poor APM best practices benchmark scores, top-scoring enterprises experience 75 percent fewer critical application problems, are 75 percent more likely to learn about performance problems proactively rather than from user complaints, and typically spend four hours resolving an application performance problem, compared to 16 hours for low scorers.

Choosing the Right APM Vendor(s) for Your Cloud Environment

Who measures performance where and why it matters
Submitted by Sevcik and Wetzel on Mon, 10/10/11 - 9:00am.

As is the fashion, application performance management vendors are now speaking "cloud". But each tool is unique, and it is challenging to see the big picture of how the current crop of APM tools fits into the often complex cloud environment. So, to identify the right application performance measurement toolkit for different situations, we have taken a stab at placing APM vendor tools into the cloud services "geography" framework we introduced in our last posting.

An APM Framework for Cloud Environments

How to measure performance when the cloud is in front of you, behind you, or all around you
Submitted by Sevcik and Wetzel on Mon, 09/19/11 - 7:14am.

When it comes to measuring and managing application performance in cloud environments, you need to look at where your cloud services are located within your application delivery system. This cloud service "geography" is critical because whether your cloud service(s) are at the back end and/or at the front end of your application delivery system will determine where and how you need to measure performance--and where you measure will dictate what application performance measurement toolkit is right for you.

Top Five APM Vendors by Performance Results

NetScout, BMC and NetIQ most used among top performers
Submitted by Sevcik and Wetzel on Mon, 06/20/11 - 10:29am.

If you want the performance of your networked applications to place you at the top of the charts you should have two or three performance management tools as we described last week. But which vendors are likely to get you the best results? Our APM enterprise benchmarking survey results shed light on that question.

'The More the Merrier' Doesn't Apply to Management Tools

Two or three performance management tools are all you need
Submitted by Sevcik and Wetzel on Mon, 06/13/11 - 8:55am.

You may be yearning to buy management tools from yet another vendor, but NetForecast's recent survey of performance management best practices and their results shows that using more management tools is not necessarily better. Most high-performing enterprises use two or at most three vendors, while low-performing enterprises use one or two. The takeaway is that most enterprises need at least two and no more than three vendors to achieve good application performance results. And if you have stellar best practices, you can get by with one vendor.

Study Shows Need for Infrastructure Plus Application Performance Views

Infrastructure and Application Performance Monitoring: You Shouldn't Have One without the Other
Submitted by Sevcik and Wetzel on Tue, 06/07/11 - 12:37pm.

Many enterprises zero in on watching either infrastructure or application performance. Based on results from NetForecast's latest application performance management benchmarking survey, we can unequivocally say that those with a "stereoscopic" view of infrastructure as well as application performance achieve dramatically better results than those with a "monoscopic" view of just one or the other. So if you are focusing on only one view, we suggest you get with the program and expand to a more holistic, dual view of performance. Here's the data that shows why this is smart.

"ITIL-Lite" for APM

A simple effective way to proactively manage performance
Submitted by Sevcik and Wetzel on Mon, 05/23/11 - 6:14pm.

If you work in a big organization replete with financial and human resources, ITIL may be your best bet for structuring your application performance management. But if your organization is like most, and you don't have the wherewithal and time to implement full-blown ITIL, we suggest a much more practical and less onerous approach to managing application performance. At NetForecast we call it "ITIL-Lite" for APM.

NetForecast Survey Shows Good APM Process Gets Results

Good APM best practices improve benchmark scores 75 percent in key areas
Submitted by Sevcik and Wetzel on Mon, 05/16/11 - 9:09am.

Data from NetForecast's recently-completed APM best practices benchmarking survey definitively show that good APM processes deliver results. In fact, enterprises with best practices benchmark scores above six (on a 10-point scale with 10 being best) report 75 percent better results in three key performance areas than their counterparts with scores under five.

Management Vendors Fail to Measure “Real” User Experience

Submitted by Sevcik and Wetzel on Mon, 03/07/11 - 6:33am.

We have a problem Houston. IT managers want to measure their users' real experience, but the vendor-supplied tools at their disposal do not spit out the measurements they need. Here's why we make this heretical statement. In a survey of 364 IT managers about their APM practices we did for a recent Network World article, we asked them to rate the importance of measuring 12 application performance attributes--and to tell us if they actually measure those attributes.

Internet Shutdown Can It Happen Here?

We like to think the US is immune from government interference with the Internet--but is it?
Submitted by Sevcik and Wetzel on Wed, 02/02/11 - 2:04pm.

We normally weigh in only on technical aspects of application performance, but as the Internet shutdown in Egypt shows, equally important to application performance are the legal, regulatory and political environments in which the networks operate. When Internet users' interests are subjugated to government interference, it's not merely annoying, it can bring entire economies to a standstill. When Internet connectivity was cut, Egypt's economy seized up, and international commerce was affected. Now that is an application performance-related issue!

W3C Defining New Metrics to Measure Web User Experience

What will we do will all this Web metric data?
Submitted by Sevcik and Wetzel on Mon, 01/31/11 - 7:19am.

 

The W3C's Web Performance Working Group is working on a specification to define 20 very fine-grained metrics to measure the duration of just about every aspect of a website user's "navigation" experience imaginable. The W3C's working draft of the Navigation Timing Specification is in the "last call for comments" phase, and once it is finalized, it will specify 20 measurements for every page rendered. That's a lot of measurements!
