Web Performance is the most sought out goal today in our fast paced computer world. Having the knowledge to create your website remains an utmost importance to those who are trying to succeed. Keeping up with the making of a website is common, and load testing is critical and necessary to improve a website. What is load testing? It is pushing a software system to its limits and measuring its responses at reasonable speeds and beyond for high/low peaks, known as stress testing. You can learn more about that here:
Today's performance on a website is a top priority because of continuous online competition that needs improving on an almost daily basis. Computers pretty much supplement our everyday lives, and it is important to improve performances with minimizing or optimizing data that can be download to improve code efficiency and faster service.
Running tests that show delay or where the load is will help improve time with faster results for upgrading (according to LoadView-Testing).
18 tips that will contribute to speed/performance on your website are:
- Image Optimization- Increase speed/minimize the size of pages.
- Reduce Http Requests-meaning more HTTP requests your web makes, the slower it will load.
- Critical Path and Render Blocking Resources-speed of web pages/causes that prevent the DOM
- Reduce Latency with a DCN-content delivery network increase
- Time to First Byte-measurement of the responsiveness of a web server.
- Avoid 301 Redirects-performance killers, will generate additional route time
- Caching-leveraging assets that rarely change
- Prefetch and Preconnect- saves time, resolves domain names before a user follows a link
- HTTP/2-dealing with a lot of images/excels HTTP/1
- PHP7 and HHVM-components server up to date
- Web Font Performance-custom fonts
- Hotlink protection-preventing others from embedding your assets
- Enable Gzip Compression-compresses web pages
- Infrastructure-a fast web host
- Fix 404 Errors-missing files 404 HTTP error
- Serve Scaled Images-saving space
- Data Optimization-cleaning old tables/creating indexes for faster access
