Flash cut in half in 2 years – now only 7% of average web page size

Posted by Pingdom

We know that webpages on average are getting bigger, and that Adobe Flash is slowly fading away. But even if we tell you that the average web page has since 2010, grown from 702 kB to 1,090 kB, wouldn’t it be even better to visualize it?

Of course it would! So, with the help of data from the HTTP Archive, that’s exactly what we’ve done.

Web pages are getting bigger

First, let’s look at how the individual components of web pages tracked by the HTTP Archive have developed since November 2010. We can see that images have taken off quite dramatically in size, as have scripts. There appears to be a noticeable decline in the size of Flash files. When it comes to HTML, stylesheets and the rest, there doesn’t seem to have been much change.

If we instead aggregate the data, basically stack each type of content on top of one another, we get a much better sense of how much bigger the average web page is today.

But relative size has changed very little
If everything except Flash is growing, what is growing the most? Measured in kilobytes, as you can see above, it’s clear that images are getting larger in combined size as are scripts.

But what if we instead look at what percentage out of the average web page is HTML, stylesheets, images, etc?

In this view, where 100% represents the total size of a web page, we can see that scripts and images increase some in relative size, and that stylesheets, as well as HTML, has lost out a bit in relative terms. The biggest change, however, is Flash, which has seen its share of the typical web page almost cut in half.

For each type of content, here is the change from November 2010 to July 2012:

  • Images: from 59% to 63%
  • Scripts: from 16% to 19%
  • Stylesheets: from 4% to 3%
  • Flash: from 13% to 7% (in absolute terms, Flash has “only” been reduced from 90 kB to 81 kB)
  • Other: unchanged at 3%
  • HTML: from 5% to 4%

What will it look like in another two years?
From this quick comparison, it’s clear that images and scripts take up, relatively speaking, a larger portion of the complete size of websites today, and Flash is slowly disappearing. And when you put Flash against the seemingly ever-increasing size of web pages, Flash is losing out even more.

We will certainly keep an eye on how this develops. If we do a follow-up study in 2014, what do you think will be the main changes? Surely, Flash is still around, but how small.


Are your web and mobile apps ready for the revolution?

From Compuware APM blog by 

Today, more than 50% of Americans own a smartphone. They use them to update Facebook profiles, scan and deposit checks, find restaurants and more often than not work.

As a result of today’s workforce becoming more dispersed and collaborative, employees often want to use technologies of their choice, including their own personal devices. Businesses have been quick to embrace this trend and give employees the ability to perform critical business functions anytime, anywhere, in the hopes of leveraging gains in productivity.

A recent study by Forrester Research shows that 60% of employees use their personal mobile devices at work. Some organizations have reported over 75% of devices on their networks are owned by employees. While this trend is viewed by some as risky and painful, causing security, liability, and management issues, others have embraced it.

Companies that have embraced Bring Your Own Device’ or BYOD have opened up a Pandora’s box of potential technical issues, only some of which have come to light. Recently IBM’s CIO tightened the company’s BYOD restrictions on certain software apps, citing security problems. A Cisco Systems study also revealed BYOD is creating internal support issues at many enterprises.

While BYOD offers flexibility, freedom and potential productivity gains, it also increases the complexity at the edge of the Internet.  To make matters more challenging, employees have the expectation that they can access their email, Internet and corporate resources not only from their laptop, but also on their iPhone, iPad, Android device or Blackberry.

It is not unusual to see the number of mobile clients in an enterprise double, or even triple, with the same number of employees, since each user may have two or even three devices in use, such as a laptop, smart phone and tablet. Employees also expect to receive the same high level of user experience, in terms of seamless access and wire-like performance that they receive with the services that they are used to consuming on their mobile devices.

Arguments for allowing employees to bring their own devices into the office environment abound – from helping employees become more productive, to making it easier to attract and retain talent, to simply submitting to a tidal wave of change that is impossible to resist.

However, the chart below provides a snapshot of just one culprit that can impact employees’ user experience – the large number of web browsers and how differently they perform on various mobile and desktop devices. This small sample shows average page load times for just a few of the hundreds of possible device/OS/browser combinations.

Since many applications are delivered via the web (and much of the work of an application happens within the browser itself) how can an IT department ensure the application speed and availability that the business demands for so many variations? The first step is to gain visibility into the performance of business sites and applications across all devices and networks used by employees.

But tracking and managing performance levels is now exponentially more difficult as more and more devices and applications are in play. If you can’t verify the reliability and performance of mobile sites and applications, then you’ll create frustrated, non-productive employees.

Visibility into application performance across networks and devices is needed to understand and track performance, quickly spot problems and correct issues before they impact employee productivity or result in unwanted support tickets.

Simplifying network and application performance

From Compuware APM blog by Kieran Taylor

Ten years ago, the main goal for managers in network operations was to ensure the network was simply up and running. Today a well performing network does not guarantee that critical business applications are being successfully delivered to users.

The reality for IT and operations is dealing with requests for faster, always available applications and as a consequence organizations are converging network and application performance to optimize delivery of business-critical applications and services.

Many IT organisations have defaulted to component-level monitoring of the network, servers and database tiers that lead to incomplete views of application performance. Network-centric approaches to monitoring have traditionally lacked insight into overall application performance and what really matters: the end-user’s experience.

And the reverse has been true too.  Traditional application performance monitoring solutions have been unable to monitor and diagnose network performance issues. When Application Performance Management (APM) and Network Performance Management (NPM) reports are unified and delivered in context to one another, mean-time-to-resolve (MTTR) is reduced, performance management costs are slashed and deployment is simplified.

As part of our APM Spring 2012 Platform Release, today we introduced new innovations in our Data Center Real User Monitoring solution which integrates APM and NPM to tackle the increasing challenges of complex, multi-tier data centers. 

Using a single device and a unified reporting interface for best-in-class application and network performance management, Compuware APM enables IT and operations experts to tackle the increasing challenges of complex data centers. Our single solution manages both application and network performance and includes:

  • A single point of instrumentation: reduces costs and delivers network diagnostics in context ofapplication performance;
  • Private cloud and virtualization ready: delivers the industry’s most complete coverage for cloud and virtualized infrastructure, introducing support for Cisco VNTag, and extended support for Citrix XenApp, VMWare vSphere and IBM AIX Micro-partitioning;
  • Auto-correlated code-level analysis: provides drill-down to application root cause in seconds via fully integrated dynaTrace PurePath analysis;
  • Integrated synthetic monitoringdelivers proactive monitoring for web and non-web applications;
  • New pricing and entry-level offerings: enables single application and project-based deployments, with seamless extensibility into a comprehensive APM solution; and
  • 100+ improvements to monitoring 30+ enterprise application environments: including SAP, Microsoft Exchange, Oracle E-Business, IBM DB2, IBM WebSphere MQ, SQL, HTTP/S and others.

This release also introduces new pricing and entry-level offerings that allow IT teams to easily start with a single application, then seamlessly and cost-effectively scale to enterprise-wide deployments.

Uswitch UK Report reveals drop between peak and off-peak surfing

From the BBC on 16 November 2011.

UK broadband speeds drop by an average of 35% from their off-peak highs when most people are online in the evening, according to a report.

The research, conducted by the comparison site Uswitch, was based on two million broadband speed tests.

The peak surfing times between 7pm and 9pm were the slowest to be online, the report said.

There were also huge regional variations between evening and early morning surfing times.

The report suggested the best time to be online was between 2am and 3am.

Users in Evesham, Worcestershire, fared worst, according to the survey, with a massive 69% drop-off between off-peak morning and evening surfing.

Those living in Weston-super-Mare did little better with speeds falling from an off-peak average of 9.5Mbps (megabits per second) to 3.4Mbps in the evening – a 64% drop.

The difference was often most noticeable in rural areas where even peak speeds were relatively slow. In Wadebridge, in Cornwall, speeds nearly halved from 4.1Mbps at off-peak times to 2.1Mbps at peak times.

“It really is surprising just how much broadband speeds fluctuate at different times of the day, with drop-offs of almost 70% in some areas of the UK,” said Uswitch’s technology expert Ernest Doku.

“Not many internet users enjoy the maximum headline broadband speeds offered by providers, and certainly not during the working week,” he added.

New rulesBroadband speed is becoming more important as bandwidth-hungry services such as on-demand TV become more popular.

Telecoms regulator Ofcom recently revealed that British households download an average of 17 gigabytes of data every month over their home broadband connections.

That monthly data diet is equivalent to streaming 11 movies or 12 hours of BBC programmes via iPlayer.

Critics say consumers are being misled by internet service providers who continue to advertise their maximum broadband speeds, even though many users do not get them.

New rules from the Committee of Advertising Practice (CAP) say that from April next year providers will no longer be able to advertise maximum speeds for net packages unless 10% of customers receive them.

Almost half of broadband users are now on packages with advertised speeds above 10Mbps but the average broadband speed is 6.8Mbps according to Ofcom.

Why Websites Are Slow & Why Speed Really Matters

Published by Mashable 6th April 2011

What a difference a millisecond can make. When it comes to browsing the web, every tiny moment counts — and the fewer moments that pass between a mouse click and a fully loaded page, the better.

Speed is a bit of an obsession for most web users. We fret over our Internet connections’ and mobile connections’ perceived slowness, and we go bananas for a faster web browser.

Given this better-faster mentality, the consequences for slow-loading pages can be dire for site owners; most users are willing to navigate away after waiting just three seconds, for example. And quite a few of these dissatisfied users will tell others about the experience.

What’s more, our entire perception of how fast or slow a page loads is a bit skewed. While we’re waiting for a site to materialize in a browser tab, pages seem to load about 15% slower than they actually do load. The perception gap increases to 35% once we’re away from a computer.

But for the precious milliseconds site owners can shave off page load times, they can see huge returns. For example, Amazon.com increased its revenue by 1% for every 100 milliseconds of load time improvement. And Aol said its users in the top 10% of site speed viewed around 50% more pages than visitors in the bottom 10%.

Site optimization firm Strangeloop has provided us with a slew of graphically organized stats on just how long pages take to load, why they take as long as they do, and just how long the average Joe or Jane is willing to wait around for your site.

Check out the infographic below.
