How Many Virtual Users Do I Need?

Once the number of users/transactions has been validated in the previous step, we only have to transform this number into virtual users (Threads) in JMeter.

Caution

Do not forget to take into account the requests made by bots (Qwantify (Qwant Bot), Google Bot, Bing Bot, and so on) in the calculation of the number of users.

The maximum number of virtual users configurable per injector depends on:

• The test plan (simple or complex, well or badly written)
• The number of listeners and their nature (some require more resources, so if we set too many virtual users, we run the risk of having a performance problem at the level of the injector, thereby distorting the results)
• The JMeter execution type (GUI or CLI mode (also called Non-GUI mode in JMeter))
• The resources made available for the test (number of servers, processor, memory, network, and so on)

The maximum number of virtual users is therefore limited by the available resources (injector&apos...
