It was time to do a complete overhaul of our website for a considerable update. We reviewed lots of online hosting websites and came to the decisions we should use Hostgator for this website. It had a promise of hosting many websites on a rather low cost plan and was rated well for website speed and recommendation by many others.

Firstly, we installed a WordPress site with the one click install and then acquired a theme that we wanted to build the website. This was the base install with an overlay of different content but there was no changes to images or any other aspect of the website.

We then ran a speed test and obtained a speed score from googles site speed test of 5.7 seconds to completely load the website until useable. This was not a good result as the recommended webpage load speed is under 3 seconds. 3 seconds has become the limit and a webpage should load with 1 – 2 seconds. As a digital agency, we won’t rest until your website loads in under 3 seconds.

Google Performance increase
Google page speed test shows a poor performance

Although 5.7 seconds was not ideal from a search engine ranking point of view but loading the webpage in Australia and the distance it was from America caused the loads to be up to 12 seconds to load the page. One of the most signification factors from this speed test was that the initial HTML document was taking 1 second just to return, then the page was downloading all the remaining resources after.

It is important to note that during all of these tests disable cache was turned on to ensure I was acting as a new user viewing the site. Returning users will always get a faster experience since their web browsers have already downloaded many of the images, fonts and javascript. These are normally the largest items to download. Therefore using the cache would have shown better results but they would have been false positives.

The first test we ran to improve the speed of the website was to move to self hosting the platform on an AWS Sydney server. We used as the url so that our main site could continue operating as normal. Moving the server to Australia would test the change in speed relative to Australia with the exact same install as hostgator.

Unfortunately it took a little time to discover the results are presented for mobile. So in the below screenshots the times are quite large, as google indicates mobile speed load time is slower (This is an assumption by google, whereas Australia has a relatively fast mobile network). However it shows that the tests between the two actually show the new server a little slower than when hosted by HostGator. However, it had reduced the load speed of the webpage in Australia from 12 seconds to over 3 seconds. This was a significant improvement for our customers in Australia.

Poor website performance on AWS (Mobile website version)

What this revealed is that the American speed of the website had increased slightly, but the increase in Australia accessing the website was greatly improved.

This turns to improved wordpress speed by over 300% gain for our Australian customers and a 8% increase in speed for America. It would also be safe to say that the website speed wouldn’t have changed much for other countries around the world.

Although we had a 320% speed increase for Australian customers. The original 12 seconds load for a website was simply unacceptable. Now that the webpage loads in under 4 seconds around the world, this had only achieved an averagely acceptable performance. We were not happy with this result.

We then decided to implement AWS cloudfront as our CDN or Content Delivery Network. A CDN is used to distribute all the resources around the world like Images, Styles, Fonts and anything else on your page that doesn’t need to change between requests for the website.  We chose to use the plug in w3 total cache for this process, which has been a great choice. CDN’s come in two types. The operate as either a push or a pull. A pull is when the CDN pulls files from your server upon a website request and then stores them. Setting up a pull CDN in cloudfront is simpler, which means less can go wrong. However it doesn’t guarantee the same speed for every user. The second website request benefits from the first request that did the initial pull. I wasn’t going to risk that when the search engines index my site and performance a speed test they get bad results due to being the first request. This meant we opted for introducing the cloud front CDN as a push model. Every time a change is made to the website, the server pushes that change to the CDN.

This proved to be complicated and many tutorials online had gotten half way through this process and given up, because troubleshooting the issues was difficult.

There will be an upcoming article on the exact settings that were used to complete the working model of the push model for CDN with w3 total cache used. There are a lot of changes to the initial installation of this plug in that increased performance. We had configured the static files to be pushed to AWS storage, then we route the requests via Cloudfront to either the server or the cloud storage depending on what time of file was required and where it would be located.

It was now time to see the end results and what performance we had achieved. The site was now loading the first page in 1.7 seconds according to google page insights. This is an improved wordpress speed by over 330% from google speed insights. This is a helpful resource when search engines are deciding which service to rank, that they see a well optimised website. In Australia this website was loading even faster due to the AWS sever located in Sydney. We were seeing 1.2 -1.5 second downloads for the initial page. This is a 1000% website speed increase for our Australian customers!

We have since noticed that the website load speed we obtained was partly helped by the failure for the CDN to cache the fonts included in the website. The theme we purchased had an unnecessarily large font package and getting this resolved increased the website to load in 3.7 seconds on google page insights and around warren in 2.5 seconds in Australia. Although these numbers are acceptable, we will be working to resolve the font issue and ensure we are back to incredible speeds on the website.
