CPU Cache是为了加速内存的访问,而TLB是为了加速virtual address到physical address的转换。 这两种cache又是相互关联的,如下图: 有关两者更详细的介绍,可以看下下面这篇文章(也可以点击阅读原文): https://www.geeksforgeeks.org/whats-difference-between-cpu-cache-and-tlb/...

Additional memory is needed for applications to cache the data. What if the cached data is updated? How to invalidate the cache? (Needless to say now that caching works great when the data to be cached does not change often) We need to have Eviction Policies (LRU, LFU etc.) in place ...
You can do caching on multiple layers of your application. Databases have their cache storages,application caches some data in the operation memory, a web client also reuses information on its side. As you may know, the HTTP protocol is responsible for network communication. The caching mechanism...
