Nevitech IT Solutions Ltd discusses the ImageSharp image cache issue in Umbraco sites, which can exceed storage limits due to untrimmed cached variants. They introduce Umbraco.Community.ImageSharp.TrimCache, a free package that automatically trims the cache by age, ensuring efficient storage management on both self-hosted and Umbraco Cloud sites.
Scheduled, age-based trimming of the ImageSharp.Web image cache for Umbraco.
The new HybridCache implementation in Umbraco enhances scalability by reducing memory usage and startup time, allowing for more efficient content loading. However, it shifts costs to certain operations, necessitating more intentional development practices. Developers should consider alternative tools for specific tasks, promoting better performance and adaptability for large sites.

In the UmbraCare blog, Piotr Bach and Wojciech Tengler discusse the process of rebuilding the database cache in Umbraco v13, highlighting the lack of visual feedback and logging during the operation. This absence complicates monitoring and verifying the rebuild's completion, suggesting that improved logging and UI feedback would enhance usability and reliability.
In Umbraco 15, caching has evolved from loading all content into memory at boot to a more efficient on-demand system, seeding a subset initially. Custom cache warm-up can now occur in the background, enhancing site responsiveness. Kenn Jacobsen emphasizes careful caching strategies to optimize performance without overloading memory.
