Abstract
A system is described for high-performance delivery of applications via attachable application storage volumes (ASV), particularly in cloud-based VDI environments, by precaching application data that is determined by learning the application behavior. Data blocks for files that are likely to be used by the application are prefetched and cached by virtual machines before the application requests those blocks so that the relevant data is instantly available in memory when required without needing to wait for the data to be transmitted from the ASV. In order to efficiently prefetch content, the read pattern for application files and their corresponding blocks is inspected. This information is used during application delivery after a user logs onto the virtual machine to selectively prefetch those blocks from the ASVs. As a result, when the user launches those applications, the system avoids the performance penalty of reading those blocks from the ASV.
