Many friends who do architecture design, program development, operations, technical management may have such confusion more or less: How many connections does SQL Server support for concurrency? Can SQL Server meet existing applications? How many connections are supported by the existing technology architecture? How many concurrent connections can theoretically be supported in the case

1. The use of testing tools to simulate multiple end users concurrent testing; The disadvantage of this test approach is that end users are often not directly connected to the database, but rather pass through one or more intermediary services, so it is not guaranteed to access the database or concurrency. Second, this test method needs to wait until the client program, the server-side program is complete

at the beginning of the Skip,take function paging, all values will be stored in data, in fact, this statement will be deferred to a foreach or ToList () call to execute. and var data = (from DB. Log Select D) Skip (20). Take (10); After the statement is executed, the program simply generates a perfect SQL statement waiting to be executed until ToList () or foreach appears, that is, waiting for the program to fetch the data before starting the databas
