In what units are performance parameters measured?

Performance parameters are usually measured in the following units:

• Time — milliseconds (ms), seconds (s), etc. For example, system response time, query execution time.
• Throughput — the number of operations or transactions per unit of time (requests per second, operations per minute).
• Resource utilization — CPU usage percentage (%), used memory volume (MB, GB), disk load (IOPS), network traffic (Mbps).
• Latency — delay between request and response, measured in milliseconds.

For example, when analyzing the performance of a web application, you can measure page response time in milliseconds and the number of requests per second that the system can handle without degradation.
