Neo4j High Performance

In Essential App Engine, Adriaan de Jonge shows Java developers how to rapidly build complex, productionquality, performance-driven cloud applications with Google App Engine. Using a start-to-finish case study and extensive Java example code, De Jonge covers the entire lifecycle, from application design and data modeling through security, testing, and deployment. De Jonge introduces breakthrough techniques for creating applications that respond within two seconds, even on cold startup, and allow server responses in hundreds of milliseconds or less throughout the rest of the session. He also demonstrates how to avoid common mistakes that can dramatically reduce cloud application performance and scalability. He thoroughly covers state-of-the-art user...

One of the biggest developments in computer hardware in the last few yearshas been the introduction of a new generation of Graphics Processing Units(GPUs) with more power and flexibility than the CPU. Not only have GPUsrevolutionized graphics programming, now developers are starting to use themwherever substantial processing power is required, for instance in financial andmedical applications. This use of GPUs for more general purposes is referredto as General Purpose computation on GPUs(GPGPU).GPU Gems 2 continues the format of the first edition, with forty six chaptersthat detail cutting-edge programming techniques from some of the world's topexperts. It goes beyond the first volume, however, in presenting in book formfor the first time methods fo...

There are three parts to tuning an Oracle database: data modeling, SQL code tuning and physical database configuration.A data model contains tables and relationships between tables. Tuning a data model involves normalization and de-normalization. Different approaches are required depending on the application, such as OLTP or a Data Warehouse. Inappropriate database design can make SQL code impossible to tune. Poor data modeling can have a most profound effect on database performance since all SQL code is constructed from the data model. Poorly written SQL code is often a culprit of performance problems and is expensive to rectify. However, tuning of SQL code is generally cheaper than changing the data model. SQL code tends to be contained inside inde...
