Caching is a technique used in computing to store copies of frequently accessed data or resources in a location that allows for faster retrieval.
How it improves website performance
Reduced Server Load
Caching reduces the strain on the server by serving pre-generated content. This is especially beneficial for websites with high traffic or resource-intensive operations.
Faster Load Times
By serving cached content, websites load significantly faster because the server doesn't have to perform time-consuming tasks like database queries or complex computations.
Improved User Experience
Faster load times lead to a better user experience. Visitors are more likely to stay engaged and satisfied with a website that responds quickly.
Lower Bandwidth Usage
Caching reduces the amount of data transferred between the server and the user's browser. This is particularly important for users on slower internet connections or mobile devices.
Content Delivery Networks
CDNs use caching extensively by storing copies of website content in servers located across the globe. This reduces latency and improves content delivery for users in different geographic regions.
