ProjectX Blog

Rankr is back with fresh data. We’ve been having data problems with Alexa’s base data not updating their own system. It seems Alexa is OK for now.

Xlinks is a digest of interesting links from internet that ProjectX staff have found in the last week.

My post on NZ Homepage Hall of Shame has shaken things up. I’ve had a number of emails and comments on the blog. A number of sites are now actively looking at improving their page architecture.

Update: A proposal to add web compression to the e-govt webstandard ! Great news.

Kudo’s to New Zealand Herald and Vodafone for taking action and improving their pages. Their numbers now are:

I’ll be doing another audit soon to profile the rest of the sites.

In the we still haven’t learnt from our past mistakes files…

Just saw this post Software takes you to infinity and beyond on stuff. I thought that the worldwide telescope looks awesome and proceeding to download it. I thought to myself I’ll get my mother in law to install it for her grandchildren in India. And then I got to the download page and here’s what I found.

6 steps with dependencies and warnings about turning off security. There’s no way I can get my mother in law to install it. Its too complicated and too painful!

If you’re going to release software aimed at families and children then it needs to be easy to install!

I’ve just found this article about global pages sizes, its confirms some of the figures that I posted about the average size of homepages in New Zealand.

It seems that we are below the global average of 312K. The scary thing is that its grown from a 93K average in 2003! And the number of external files (JS, CSS, images) for a webpage has nearly doubled.

From the article.

“So the increase in the average speed of broadband has more than kept pace with the increase in the size and complexity of the average web page. That is one reason why broadband users expect faster response times. Yet narrowband users have experienced slower response times as web page size has increased.”

The article has some good info on, growth of media files, image sizes and average web page characteristics.

I’ve recently conducted a survey of the top 75 websites in New Zealand called the New Zealand Homepage hall of shame.

We’ve realised there is a lack of knowledge out there when it comes to make websites faster. Starting today, I’d like to annoucement that Paul Gold (ProjectX and Auric Consulting ) and I (John Clegg) will be available on a consulting basis to help companies improve their website and systems performance.

We’ve been working in a number of ecommerce companies for almost 10 years and we’re surprised at the lack of understanding of basic web and database optimisation. We given a couple of talks at WDANZ, Summer of Code and eGovt Barcamp over the past 12 months and it seems that the message is still not getting through.

Why does it matter?

“We see a direct correlation between the speed of our services and our bottom line.

Our customers seem inclined to spend a set time on our site per session – the more pages they can few in that time, the more they see and buy, and the more we earn.”

– John MacDonald – CEO Trade Me 2007

This post is Part of a web performance audit of New Zealand homepages. (Part II looks at Government homepages.)

I’ve compiled a list called the New Zealand homepage hall of shame. The list details the download efficiency of the top 75 websites in New Zealand. The survey was conducted using the YSlow tool over the top 75 New Zealand websites from Rankr.

In the results, I’ve included the YSlow ranking, total size of the webpage (this includes all html, css, flash, javascript, images etc) in Kilobytes, the number of external javascpript and CSS files and the time it would take to load on a 56k Modem (@ 6k/s).

The Highlights lowlights of the survey:

• The average size of homepages was 304.9K. UPDATE: Global webpage Average is 312K
• 52% of websites use NO WEB COMPRESSION
• The largest pages were over 1000K
• Several of the top 20 sites in New Zealand were the biggest offenders
• Advertising javascript is not being compressed
• Some sites have dozens of Javascript and CSS files, worst offender had 35 javascript files
  

A number of web companies and web developers should be holding their heads in shame – the results are not flattering. We need to better building smart – download friendly webpages not slow loading monsters ! You can either fix it yourself or get some experts!

So without further a due here are the summary tables:

Top 10 worst homepages according to Yslow ranking

Top 10 best homepages according to Yslow ranking

Top 10 largest homepages in Kilobytes

Top 10 smallest homepages in Kilobytes

Here is the complete data for the top 75 New Zealand websites homepages. I have compiled the list from using YSlow to analyse the pages and recording everything. The data is sorted by worst Yslow ranking. (The test was completed 13th of May 2008 between 8-10pm)

I been working on a mini audit of the top 75 New Zealand websites. I took the top 75 NZ websites from Rankr and using YSlow compiled the data last night.

I discovered that …

The Average homepage size in NZ is 304.9K !

That will take almost 51 seconds to load on a modem.

The size is the total downloaded size of all the total html, css, images, js, flash etc. Compressed files are recorded at their compressed size.

Even more scary is 52% of the top NZ website are not using any web compression, 37.3% are using some compression and 10.7% are fully compressed.

We can’t complain about dial up loading speed if our homepages are over 300K!

I’ll be posting the NZ homepages of shame, very shortly.

UPDATE: Global average pagesize is 312K

I’ve just been reviewing some of the recent materials by Steve Souders (previously of Yahoo, now at Google) on speeding up your javascript. He has powerpoint slides (from Web expo 2.0) on how you can load scripts in parallel and how to structure the loading of your scripts.

The powerpoint is a must for any web developer who wants to ensure their website can deliver high performance.

He reminds us that 91% of the time spent waiting for a webpage to render is spent on the the frontend. The frontend covers loading all of the CSS, javascript and images loading. The other 9% covers the request to the server and loading the base html!

This highlights the some focus on the frontend can make a huge difference in speeding up webpages.

We have no new Rankr stats this week. For the second time in a couple of weeks, the Alexa data for New Zealand has not updated. The problem has been logged with Alexa (Amazon) and we will update the data as soon as it comes available.
