Tips For Performance Testing
Check for functionalities that already come with a browser so that you can remove any unnecessary or extra code. Most of the time extra code means additional loading time.
Don’t Use Too Much Memory
Avoid Memory Leaks
If there is a memory leak, the web page continues to reserve more memory. Ultimately, this decreases the occupancy of the device’s entire memory and impacts performance.This is most likely in the case of a web page that has an image gallery or slider.
It is important to check for memory leaks and fix the issue to avoid overloading the user’s device and creating a bad user experience.
Use Web Workers For Time Consuming Code
Web Workers allow processor intensive calculations without any blockage to the UI thread. For efficient performance, Web Workers let you create new threads. You can delegate work so that long running tasks that cause a backlog can now be passed to a worker. This boosts performance and allows for a seamless user experience.
Implement Various Optimizations
- Rewrite algorithms wherever necessary to achieve the same results with lesser calculations.
- Simplify mathematical formulas as much as possible.
- Replace some operations with bit-level operators as they use lesser processor cycles.
- Use calls to functions and variables that can be repeated.
Use Application Performance Management Tools
Chrome allows you to use the “More Tools” option to check the memory and CPU usage by each tab. You can also go for an advanced analysis by using the developer tools performance view in Chrome or Firefox to analyse various metrics.
Application Performance Management tools like Retrace come with Real User Monitoring (RUM). RUM accelerates web performances by allowing you to monitor front end and back end code together. This more comprehensive perspective makes identifying bottlenecks easier and better pinpoints the correct solution. As website performance is optimized, web pages respond quicker and feel more interactive. End-users are happy, become more engaged, and ultimately, are more likely to buy.
RUM includes resource breakdowns to quickly help you identify if your images need to be optimized or if your stylesheets and scripts need to be minified or cached. RUM’s segmentation functionality allows for deeper insights. Use segmentation to monitor load times based on browser, geography, and device type. This makes it easy to identify opportunities to improve the overall experience by pinpointing optimal locations for CDNs. Try your free, 14 day Retrace RUM trial today.
The Balance Between Readability and Optimization
A successful website or app is dependent on good code, great performance and detailed performance testing. Make sure that you take care of all of these three aspects well with an application performance management tool, like Stackify Retrace.
