Which caching mechanism does Liferay utilize for performance optimization?

Liferay employs a range of caching mechanisms to enhance performance and user experience, and theme caching is one of the key strategies it utilizes. This mechanism specifically targets the rendering of themes, allowing Liferay to store the results of theme processing. When a user accesses a page with a specific theme, Liferay can quickly serve the already processed theme instead of regenerating it from scratch, reducing load times and server resource usage.

By caching themes, Liferay ensures that repeated requests for the same resources are handled efficiently, enabling smoother navigation and quicker loading of pages. This not only benefits users by providing a better experience but also minimizes the strain on server resources, contributing to overall system performance and scalability.

While user session caching, database query caching, and file system caching are important components of Liferay's caching strategy, the focus on theme caching directly relates to improving the rendering of the user interface and supporting faster response times for end-users.
