/cpu, n is the number of threads, and t is the number of physical connections created each time. The test result is about 5-10 ms, the cpu is the number of CPUs of the current machine. In addition, the server load also affects the network usage. To avoid creating as few physical connections as possible during high concurrency, we can increase the Min Pool Size appropriately, but not too large, this is because the number of TCP links for a single machi
Database Connection PoolA connection pool is a cache of database connections that request a database connection to a connection pool whenever the application needs to connect to the database, and the
. This means that many identical connections will be opened and closed repeatedly during application execution. To minimize the cost of opening a connection, ADO. NET is calledConnection Pool.
The connection pool reduces the number of times new connections need to be opened.
