WARNING: Do not follow the advice on this website.Do not make your WordPress website pages load within a second, like mine.

You will just get hate email; people will not link to you.People want their websites to load in 10 to 20 seconds.

People want to boast that they had to use unnecessary, extra software to 'cope' with their website's load, even though I proved here that the default WordPress can EASILY handle 2.5 million visitors per month.

WordPress, Drupal and Joomla ALL load within one second as documented here on this tiny 200 Mhz VPS with 87 MB of its 256 MB memory unused.

People do not like me exposing how easy and quick it is to fix a slow loading website.

You have been warned. There is such a thing as too fast, too good, too honest, too helpful.

People will continue to move from slow shared hosting to another sharedhosting, complaining their whole life, never understanding that therecannot ever be a cheap, fast, shared host with fast, good technicalsupport.

In contrast I am bored at the utterly boring regularsub-second response time of my website and its admin control panel. Thewebsite just stays up 100 percent of the time, no problems ever.

2200 WordPress, Joomla, Drupal, … Websites Load Time Comparisons

January 10th, 2009 Leave a comment| Trackback

I spend the last 2 months of 2008 running tests against CMS 2200 websites, to get an answer to:

- How fast is the average WordPress website?
- How do Wordpress, Joomla and Drupal page load times compare?
- How fast do these CMS pages download: Movable Type, PHP Nuke, Mambo, ez Publish and Plone?

This article documents the results.


CMS = content management system.

If you use, or plan to use any of these CMSs, this article is relevant to you.

Fortunately my conclusion is: all CMSs could be tuned to let your webpages download in a second or two.

So pick your CMS based on your needs: these CMS are very different from each other.

A few introductory sentences, before we view the graphs:

All tests were done at http://performance.webpagetest.org:8080/ using the fastest speed. DSL tests cause pages to download around twice as slow.

I only tested 85 Elgg pages. Once I realized these websites are allslow, I stopped testing further Elgg pages. So Elgg remain on thegraphs to show how bad things can be.

Some tests had widely different download times: I eliminated that 3.1 percent from my test results.

Websites were selected by searching on “powered by …” in google and selecting the first 300 to 700 websites for each CMS.

Unfortunately it was VERY difficult and time consuming to get 300websites representing each CMS. ( People remove the required creditlines, etc. )

So I am just using the results of the serveral hundred websites could easily get within three weeks.

Graphs ’speak for themselves’ so I have just a few comments about each.

First graph: Page Load Time

 

All graphs made with the superb gnuplot

Average page load time across all 9 CMSs tested: 5.4 seconds

Top 10 percent fastest CMS sites: 0.7 seconds

Movable Type: bottom red line. Very impressive. Movable Type has astatic publishing model build in. Obviously most people use that. Thatmakes Movable Type the undisputed champion where page load times areconcerned.

WordPress and Joomla does very well too.

After 2 seconds download time, the remaining websites quickly becomeslower: people care about download times and either have fast sites, ordo not care and have slow sites.

Speed Page Load Time (sec) Compared to Others Very Fast .5 95% of all other websites are slower Very Fast 1.1 81% of all other websites are slower Average 2.1 50% of all other websites are slower Slow 3.1 61% of all other websites are faster Very Slow 5.9 88% of all other websites are faster Very Slow 8.7 96% of all other websites are faster Very Slow 11.3 98% of all other websites are faster Speeds measured by www.alexa.com

HTML Table provided by www.pageloadtime.com

You are welcome to use this table on your website, if you keep the above credit lines.

Based on Alexa, if your website loads in more than 3 seconds you are slow.

According to Alexa, 5.9 seconds is very slow. More than 80 percent of the 2200 tested CMS sites are therefore slow.

Fact: Average time for 2200 CMSs is 5.4 second.

This study only tested the, around 300, top ranking CMS websites in each category.

Speculation: There are probably 1000s of additional CMS websites in the world.

Speculation: The overall page load time of these websites mighteasily be 8.7 seconds, making them the worst 4 percent slowest websitesin the world.

Fact: if your page load time is over 11.3 seconds, you fall within the worst 2 percent worldwide.

Some people continue to say … it is just a few seconds.

Based on you technical knowlege, it could take less than an hour tofix your website to move from a 10-15 seconds to 2-3 seconds downloadtime.

The most difficult thing is to care enough and decide to do something about it.

To make a website faster is technically easy.

Months after you have seen the benefits of your faster website, youcan make another effort, to move from 3 seconds to under a second, andbecome member of the elite 5 percent fastest websites.

You probably are not emotionally and technically ready to move from15 to .7 seconds in one go … you might still believe more content onthe home page is better, and might be unwilling to ’sacrifice’ any ofyour current content, just to have a professional, fast website.

The route to a 0.7 seconds website is a pleasant emotional andtechnical enlightenment journey. Enjoy the journey itself as well.

Second Graph: time to First Byte

Time To First Byte or TTFB is a measurement that is often used as anindication of the responsiveness of a webserver or other networkresources.

It is the duration from the virtual user making an HTTP request tothe first byte of the page being received by the browser. This time ismade up of the socket connection time, the time taken to send the HTTPrequest and the time to taken to get the first byte of the page.

http://en.wikipedia.org/wiki/TTFB

 

Average TTFB across all 9 CMSs tested: 205 ms

Top 10 percent fastest CMS sites: 69 ms

Elgg stands out again as being particularly bad. TTFB at a fast website host is less than 50 ms.

A TTFB of over 100 ms probably means you are not using the static html plugin, but PHP regenerates your webpages every time.

A TTFB of over 2000 ms means your host is VERY slow. If that time isyour TTFB for static html, you are obviously hosted at a fast freewebhost.

Third Graph: Initial Connection


 

A good Initial Connection time is 30 ms.

Except for the around 40 websites with slower than 150 ms Initial Connection times, results are remarkably consistent.

Please note that if your Initial Connection is 120 ms instead of 30ms, every one of your page objects have that 120 ms vs 30 ms times:slower times add up to cause slower pages.

Fourth Graph: Page Size

Average page size across all 9 CMSs tested: 428 KB

Top 10 percent fastest CMS sites: 143 KB

A large number of sites have home pages sizes of over 1 MB.

Notice how the top 100 sites all have sizes less than 500 KB.

Fifth Graph: Number of Requests


 

Average Number of Requests across all 9 CMSs tested: 34

Top 10 percent fastest CMS sites: 15

Mustard yellow Elgg very impressive, but extremely slow web hosts make them the worst CMS in this study.

PHP Nuke purple squares: these people like to have many objects on their webpages.

Between 200 and 320, WordPress have many websites with 50 to 150 objects on their home pages.

Lets see what those requests consist of.

Sixth Graph: Number of images

 

aahhhh, PHP Nuke likes to have many images on their pages.

Notice how the top 100 sites have mostly less than 25 images on their homepages.

Less than 25 images is impressive, since that includes gifs, jpgs and pngs.

Gifs, jpgs and pngs have different reasons for existance.

For convenience (synomyn for lazyness) I just added apples to oranges here.

Seventh Graph: Number of css

 

Even with the Drupal feature to combine css, they (brown triangle) clearly have significantly more css’s than everybody else.

Mambo does very well, with their yellow area dominating the bottom of the graph.

WordPress with blue asterisks does well with less than 5 css for nearly all 320 websites tested.

ez Publish have 5 to 15 css per home page, easily visible as the green crosses, rising above everyone else.

Eighth Graph: Number of js

 

Unfortunately many WordPress sites have more than 20 js’s per page.

Notice how the top 100 fastest websites nearly all have fewer than 7 js’s per page.

Conclusions

- Slow webhost: slow TTFB, slow initial connection, slow overall page load times

- More css, more tcp connections and sockets required; slower pages

- More js, more tcp connections and sockets required; slower pages

- More images, more tcp connections and sockets required; slower pages

- No apache expires header information: all images, and all css downloaded upon every page visited.

This study did not summarize and average the Optimization Checklist items you get at http://performance.webpagetest.org:8080/

However, overall I found that fast websites have their expireheaders set and compress their css and images, while slow websites donot have expire headers and does not compress anything making EVERYpage slow requiring everything to be downloaded for every page someonevisits on their websites.

Fast sites have more green checkmarks in their the Optimization Checklist

At the bottom of the checklist is a table explaining reasons for passing or failing the optimize tests.

Solutions

- Fewer objects per page results in faster webpages

- Subdomains results in parallel downloads of your webpage contents: resulting in faster page load times

- Set the Apache settings as referred to in the Optimization Checklist.

- Use the static cache plugin if your CMS has one

- Test your website for free at http://performance.webpagetest.org:8080/

I have free copies of these ( and several others, including acomplete WordPress-only set ) page load time graphs available from mywebsite. Anyone is allowed to use these graphs on their website, whenproviding a link to me.

So, enough from me, make your website faster and write about it.

I implemented what I preach here, and now probably have one of the fastest WordPress information site in the world.

Here are the results of testing my WordPress website - 0.8 seconds downloadtime … using Apache, MySql and PHP … no proxy, no fastcgi, no lighttpd,no Nginx.

Here are the page load time test results for the WordPress, Drupal and Joomla demos, before and after tuning.

If these demos load in 1 second, why does other people’s your pages load in 15 seconds?

You too can easily be among the top 5 percent fastest CMS websites.

Just care and do something about it … simple.
