Apart from using a service like Peakhour there are a lot of things you can do to make your site faster. A general basic overview for rendering faster in the browser would be:
- Cut down your overall page size, do this by simplifying code and minifying content
- Make sure your images are optimised.
- Eliminate any unnecessary requests to third party domains.
It is also very likely you can make some changes to improve the responsiveness of your origin server. Depending on the software you use, eg PHP, Wordpress, Magento then there are many things to check. We'll have some guides soon.
If you are on one of our plans then we are happy to look at your site to give you recommendations on what you can do.
