Was the system loaded? What were the load requirements?

System load is determined by requirements for the number of concurrent users, the volume of data processed, and response time. For example, if a system must serve 1000 concurrent users with a response time of no more than 2 seconds, this already constitutes a high load.

Load requirements are usually formulated as:

• Maximum number of concurrent sessions
• Maximum number of transactions per second
• Response time to requests
• Level of availability and fault tolerance

Stress testing and load testing are used to assess the load, helping to understand whether the system can withstand the specified parameters.
