oracle| Data | database | speed | Statistics are often used in large database systems, but for large data systems, users often feel slow to perform complex query statistics and can not meet application requirements, which requires us to design the database system in a reasonable setting, Increase the speed of query statistics. This article unifies the author's project development experience, elaborated the concrete establishment method. When we develop a large Oracle database system, we combin

SocketAsyncEventArgs buffer as a base block of memory where there is no block copy of the protocol data and the network cache read-write. If the pipestream corresponding BinaryReader and Ibinarywriter read-write specifications are used in the application, most of the data processing basically does not have a memory copy process, which makes the data processing performance more efficient. The following is the structure of the Pipestream:Performance Beetlex performance in the end, the following
