One of the most important issues that must be regarded when designing a distributed file system is performance. Existing implementations show that significant increase in performance can be achieved by using a caching mechanism. The purpose of this article is to examine various approaches on caching ...
Certificate Caching Once EFS uses a certificate, it is cached on the local machine. This eliminates the need for looking up users in Active Directory every time a new user is added to an encrypted file. Certificates that are part of a certificate chain, and self-signed certificates, can be...
The server endpoint object contains the settings that configure the cloud tiering capability, which provides the caching capability of Azure File Sync. In order to sync with an Azure file share, the storage account containing the Azure file share must be in the same Azure region as the Storage...

Caching and Data Recovery The cache is the area of RAM that contains the most recently used data. When you write data to disk, the lazy-write technique in Windows XP Professional indicates that the data is written when it is still in the cache. Cache memory can also be on the disk cont...
