Static Files vs Redis Caching: Which Is Best for High‑Traffic Pages?
This article compares static file serving and Redis‑based page caching for heavily visited sites, outlining their advantages and drawbacks such as speed, update frequency, database load, implementation complexity, and the need for dynamic processing.
Applicable to scenarios with high‑frequency access where page content needs frequent updates, such as a homepage.
Characteristics include massive traffic, a large amount of content requiring multiple database queries, and high database pressure, as well as the need to display the latest information promptly.
Using static file generation offers fast response because the server can return file contents directly without dynamic processing, but it requires frequent updates to the static files, involves more complex code logic, and incurs higher file‑handling costs.
Using Redis to store page content allows setting an expiration time of N minutes, enabling automatic content expiration without programmatic handling or file operations, making it very simple; however, it still requires the application server to perform dynamic processing.
