Memory: memory usage may be the most important factor in system performance. If the system frequently switches pages, the memory is insufficient. "Page Swap" is a unit called "page". It moves code and data blocks of a fixed size from Ram to a disk to release memory space. Although some page switches enable Windows 2000 to use more memory than actually, they are acceptable, but frequent page exchanges will reduce system

Performance counters are also called performance monitors. How is a person's health condition? We obtain relevant indicators through various health checks, such as blood pressure, heartbeat, and vital volume. In the performance test process, the software and hardware of the entire system are also essential for monitori

During this process, I noticed some very strange phenomena: even though no operations are performed in the database, there are still write activities in the database files. This situation exists in both data and log files. This situation continues even when I make sure that I am not connected to SQL Server. Since there is no connection, how can I/O
