64-bit Windows Vista supports from 8GB to 128GB (depending on the version), so applications can preload substantially more data into virtual memory, allowing rapid access and big improvements in application performance.

Applications with large data sets will see a big benefit from 64-bit servers and operating systems because, in many cases, they will be able to load the entire database into RAM. Pervasive PSQL Summit v10 includes support for Windows Vistaв„ў and 64-bit architecture. However, AWE usage has to be built into the application and this approach affects other parts of the operating system by reducing the amount of memory available to Windows and drivers. Using MicrosoftвЂ™s Address Windowing Extension, (AWE), API with Windows 2000 Server and Windows Server 2003, it is possible for 32bit applications to access more addressable memory. So, if a 32-bit Windows machine has 4GB of RAM, adding memory wonвЂ™t have any effect on performance. This means the most memory that any given application can access is 2GB. In Windows-based machines, that 4GB is split between the operating system and the applications. 00000007 SecondsДatabase Management Systems (DBMS) caching and file system caching methods 32-bit Intel and AMD machines can theoretically access up to 4GB of RAM. 013 Seconds Access Time = 70 Nanoseconds =.

On the software side, disk access also involves a вЂњsystem callвЂќ that is relatively expensive in terms of performance. After all, disk access is one of the few mechanical (as opposed to electronic) functions integral to processing, and suffers from the slowness of moving parts. It makes sense that maintaining data in memory, rather than retrieving it from disk, will improve application performance. Pervasive PSQL includes several enhancements to enable both of these approaches.Д¦4-Bit Support вЂ“ More Memory One very simple way to reduce an applicationвЂ™s disk I/O is to maximize the amount of RAM available. Since RAM access is more than 100,000 times faster than disk access, more memory and more efficient use of memory will typically improve application performance. These are: disk I/O latencies, network I/O, and processor and memory use. Performance Basics вЂ“ More Memory, Less Disk and Network I/O There are three main database-related factors that can affect an applicationвЂ™s performance. The purpose of this paper is to explain the performance enhancements of Pervasive PSQL and to act as a guide to developers, independent software vendors and end users, in understanding these enhancements and in predicting the benefits, both in performance testing and in deployment of applications in the field. PervasiveвЂ™s philosophy for increasing performance is to improve overall application performance, rather than focusing on a set of arbitrary benchmarks. For an in-depth look at PSQL performance tuning, please read Chapter 5 of the Pervasive PSQL Summitв„ў v10 Advanced Operations Guide. This whitepaper highlights some of the more important performance additions weвЂ™ve made to Pervasive PSQL and includes tuning suggestions to help you to optimize your database. Applications running on Pervasive PSQL consistently provide a great user experience because weвЂ™ve spent 25 years engineering performance improvements into each new release.
