Applies to: SQL Server all supported versions. This article discusses compute capacity limits for editions of SQL Server and how they differ in physical and virtualized environments with hyperthreaded processors. A thread or logical processor is one logical computing engine from the perspective of SQL Server, the operating system, an application, or a driver.
A physical processor can consist of one or more cores. A physical processor is the same as a processor package or a socket. Each thread of execution appears as a logical processor. For example, if your computer has two quad-core processors with hyperthreading enabled and two threads per core, you have 16 logical processors: 2 processors x 4 cores per processor x 2 threads per core.
It's worth noting that:. The compute capacity of a logical processor from a single thread of a hyperthreaded core is less than the compute capacity of a logical processor from that same core with hyperthreading disabled. The compute capacity of the two logical processors in the hyperthreaded core is greater than the compute capacity of the same core with hyperthreading disabled.
These limits apply to a single instance of SQL Server. They represent the maximum compute capacity that a single instance will use. They do not constrain the server where the instance may be deployed. The following table specifies the compute capacity limits for a single instance of each edition of SQL Server:.
This licensing is not available for new agreements. There are no limits under the Core-based Server Licensing model. In a virtualized environment, the compute capacity limit is based on the number of logical processors, not cores. The reason is that the processor architecture is not visible to the guest applications. For example, a server that has four sockets populated with quad-core processors and the ability to enable two hyperthreads per core contains 32 logical processors with hyperthreading enabled.
In simple terms the DB can't grow past 10GB total in size, but will contine to write to the database untill the used space also reaches 10GB. Azure Blob download using PowerShell. Test if any SQL Server related questions already exist. SharePoint Max pool size was reached. Skip to main content. Find threads, tags, and users Couldn't find an answer anywhere and it will be useful for monitoring purposes. However, the further you move above and beyond the below guidelines, the more likely that you will encounter the limitations of the free version of Microsoft SQL Express.
Potential performance issues increase directly with the number of users, particularly if the users are very active. Your database is over 2GB in size. You have contacted Customer Support to review performance issues and no issues with the program can be found. System Information Last Published Date.
