In order to overcome these issues, the concept of paging and segmentation was introduced, where physical address space and virtual address space were designed. Here, memory is divided into equal sizes of partitions where the code of a program resides. A detailed description of these concepts is below.

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking.

If the sleeping session has an open transaction, it is always related to code and not SQL Server. The timeout is not SQL Server related, it is set by the.NET client and the CommandTimeout property, so that too is code related and not SQL Engine related behavior.
