What is item cache in Sitecore?
Sitecore uses various caches to store data, rendered presentation logic and other information in memory in order to improve performance and response time. A cache is a dictionary that keeps track of when each entry is accessed. The data that is stored for each entry depends on the cache.
Which cache is based on per managed database in Sitecore?
Prefetch Cache Prefetch caches contain items that Sitecore accesses during and immediately after initialization and items with children that Sitecore often accesses as a group. Sitecore maintains those caches over the life of the application. Each database prefetch cache entry represents an item in a database.
How Sitecore cache works?
Sitecore caches two copies of the output: one for authenticated users, and one for unauthenticated users. Sitecore caches output for each parameter the rendering accepts. Sitecore caches output for each unique combination of query string parameters. Sitecore caches output for each authenticated user.
What’s the difference between a cache and a prefetch?
(computing) A fast temporary storage where recently or frequently used information is stored to avoid having to reload it from a slower storage medium. (geocaching) A container containing treasure in a global treasure-hunt game.
What’s the difference between preload and prefetch in HTML?
Preload is different from Prefetch in that it focuses on fetching a resource for the current navigation. prefetch focuses on fetching a resource for the next navigation. preload is a new web standard that offers more control on how particular resources are fetched for current navigation.
What’s the difference between prefetchnta and prefetcheder?
The PREFETCHNTA instruction is basically used to bring the data from main memory to caches by the prefetcher, but instructions with the NT suffix are known to skip caches and avoid cache pollution. So what does PREFETCHNTA do which is different from the PREFETCH instruction?
When does Sitecore access the database prefetch cache?
Database prefetch caches contain items that Sitecore accesses during and immediately after initialization, and items with children that Sitecore often accesses as a group. Sitecore populates database prefetch caches at application initialization, and maintains those caches over the life of the application.
