Every website developer has heard this question before at one point or another. By no means does it mean your site is built in a bad way. If might even have used a great framework, image sprites, CSS and JS compression and a stack of other speed increasing tools! But, if you have a website that has a lot of functionality on every page with lots of images, calls to the database or integrations, dynamic content, it will be slower than a simple static website.
This is where caching comes into play.
There are a myriad of different forms of caching tools at a developers disposal. There are tools to save sessions, images, and even entire pages into a much quicker readable format to display your website faster to your customers. And as long as they don’t conflict, you are able to use as many of these tools as desired within your budget and timeframe.
Use of a CDN to save images is one of the current trends. Saving the images that have already been hit by previous customers to show to all future customers much quicker always sounds like a good idea. But a CDN does more than that! As the images are coming from a different server, or possibly multiple other servers, your customer’s browser will import all the images and static files at once, rather than the browser’s limit of 5 per server. You can immediately see how this would help.
Having a full page caching tool to use on your website means that you can turn a fair chunk of your website into what seems like a static website! Imagine having a dynamic website with all the functionality that you need and want displaying at the same speeds that a static website displays. Seems like a dream, and it can come true. The value is in the investment, and the increased conversion as a result from that time and money invested into the tool will prove worthy.
Having a quick website is what every customer and retailer wants and every developer strives for. So why not have a go at implementing different levels of caching on your site today.
