program runs under User mode, while the operating system code runs under kernel mode. The code in Kernel mode allows access to all system memory and all CPU instructions.
Under User mode, HTTP.sys receives an ASPX HTTP request, and then it views the application Pool that is based on the request's application according to the Metabase in IIS, if the Application pool does not exist, it is created. Otherwise, the request will be sent directly to the queue corresponding to application Pool.

index index_headers_id on headers (ID)Then execute the above query statementSelect Id,buydate from Headers where buydate> ' 2008-12-28 'Analysis: Does it feel strange? Not surprisingly, because the overlay column of a nonclustered index contains the key columns of the nonclustered index, the columns that the nonclustered indexes contain, and the key columns of the clustered index. Therefore, IDs and buydate overwrite columns for nonclustered indexes, so the results can be found only through the

Label:Original: Initial SQL Server performance issue (3/4): List blocked sessionsIn the initial SQL Server performance issue (2/4), we discussed the list of waiting resources or running session scripts. In this article we will look at how to list blocked sessions with specific information. 1 /***********************************************************************
If you design a server program that starts a thread whenever a user request is processed, it will consume the server's resources on a certain program. One of the best ways to do this is to create some thread objects in advance before the server starts, and then, when processing client requests, get the thread objects from the built threads and process the request
SQL Server Performance Tuning 3 Index MaintenancePreface
The previous article introduced how to improve database query performance by creating indexes, which is just the beginning. If you do not need proper maintenance in the future, the indexes you have previously created may even become a drag-and-drop attack and a helper for database performance degradation.Search for fragments

We noticed that anonymous users whose host field is localhost have all permissions! That is to say, a local user can log on to the MySQL database server with an empty username and password to obtain the highest permission! Therefore, anonymous users must be deleted!

Do not forget to use flush privileges to forcibly refresh the memory authorization table after the user table operation.

performance gains of indexes, it's very difficult to actually build enough correct and necessary indexes at the outset, how can we infer which tables need to be indexed and which ones are not built correctly?Typically, SQL Server executes a query script with an existing index, assuming that no index is found he will voluntarily generate one and store it in the DMV (dynamic management view).This information is purged whenever the SQL

That method will wait for a while. this action is called blocking. the accept () method will block the server thread until a call arrives. after the five connections are closed, the server exits. any call in the queue will be canceled.
