An client-side performance optimization system for streamed applications provides several approaches for fulfilling client-side application code and data file requests for streamed applications. A streaming file system or file driver is installed on the client system that receives and fulfills application code and data requests from a persistent cache or the streaming application server. The client or the server can initiate the prefetching of application code and data to improve interactive application performance. A client-to-client communication mechanism allows local application customization to travel from one client machine to another without involving server communication. Applications are patched or upgraded via a change in the root directory for that application. The client can be notified of application upgrades by the server which can be marked as mandatory, in which case the client will force the application to be upgraded. The server broadcasts an application program's code and data and any client that is interested in that particular application program stores the broadcasted code and data for later use.

A method for maintaining a cache of dynamically generated objects. The method includes storing in the cache dynamically generated objects previously served from an originating server to a client. A communication between the client and server is intercepted by the cache. The cache parses the communication to identify an object determinant and to determine whether the object determinant indicates whether a change has occurred or will occur in an object at the originating server. The cache marks the object stored in the cache as invalid if the object determinant so indicates. If the object has been marked as invalid, the cache retrieves the object from the originating server.

A method for providing “guaranteed message delivery” for network based communications between a client machine and a server. The client machine includes a Client Runtime Environment (CRE) and the server includes a Server Runtime Environment (SRE). The method includes the following steps. A first message queue is maintained in the CRE. A first unique identification is attached to the first message from the first message queue and the first message is sent from the CRE to the SRE via a network communication. The SRE receives the first message and sends an acknowledgement of the receipt of the first message to the CRE. Upon receiving of the acknowledgement within a certain time threshold, the CRE removes the first message from the first message queue in the CRE. A method of providing “server-push” of messages from the server to the client machine utilizing a push Servlet and a push API.

A computing system for performing stateful distributed computing includes a client machine having a Client Runtime Environment (CRE) that is adapted to maintain the state of an application in the client machine. The CRE maintains state of the application by first retrieving a first markup document of the application, creating and storing a first object oriented representation of information contained in the first markup document. The first object oriented representation defines a first state of the application. Next, retrieving a second markup document, creating and storing a second object oriented representation of information contained in the second markup document. Finally merging the first and second object oriented representations thereby forming a new object oriented representation of information contained in the first or the second markup documents. This new object oriented representation defines a new state of said application. The CRE may further update the new state of the application by retrieving one or more additional markup documents, creating and storing one or more additional object oriented representations of information contained in the one or more additional markup documents, respectively, and merging the one or more additional object oriented representations with the new object oriented representation thereby forming an updated state of the application.

A system and method for dynamically selecting the data fetch path for improving the performance of the system improves data access latency by dynamically adjusting data fetch paths based on application data fetch characteristics. The application data fetch characteristics are determined through the use of a hit / miss tracker. It reduces data access latency for applications that have a low data reuse rate (streaming audio, video, multimedia, games, etc.) which will improve overall application performance. It is dynamic in a sense that at any point in time when the cache hit rate becomes reasonable (defined parameter), the normal cache lookup operations will resume. The system utilizes a hit / miss tracker which tracks the hits / misses against a cache and, if the miss rate surpasses a prespecified rate or matches an application profile, the hit / miss tracker causes the cache to be bypassed and the data is pulled from main memory or another cache thereby improving overall application performance.

A remote replication solution for a storage system receives a stream of data including independent streams of dependent writes. The method is able to discern dependent from independent writes. The method discerns dependent from independent writes by assigning a sequence number to each write, the sequence number indicating a time interval in which the write began. It then assigns a horizon number to each write request, the horizon number indicating a time interval in which the first write that started at a particular sequence number ends. A write is caused to be stored on a storage device, and its horizon number is assigned as a replication number. Further writes are caused to be stored on the storage device if the sequence number associated with the writes is less than the replication number.

A kernel-mode graphics driver (e.g., a D3D driver running under Microsoft Windows) exploits the parallelism available in a dual-core computer system. When an application thread invokes the kernel-mode graphics driver, the driver creates a second (“auxiliary”) thread and binds the application thread to a first one of the processing cores. The auxiliary thread, which generates instructions to the graphics hardware, is bound to a second processing core. The application thread transmits each graphics-driver command to the auxiliary thread, which executes the command. The application thread and auxiliary thread can execute synchronously or asynchronously.
