How does JMeter
work? JMeter works by simulating multiple users
(threads) making requests to a target server. Each thread executes a test plan,
which consists of one or more samplers that generate requests, and one or more
listeners that collect and display results. JMeter can also simulate different
network conditions and measure server performance under various loads.
4.

Control the flow of requests and actions within a thread.
·
Samplers: Generate
requests to the server.
·
Timers: Introduce
delays between requests.
·
Assertions: Verify
the response of a request.
·
Listeners: Collect
and display test results.

100. How do you distribute load across multiple
servers in JMeter? To distribute load
across multiple servers in JMeter, you can set up a distributed testing
environment with multiple JMeter instances running on different machines.
Configure the JMeter instances to work together as a cluster, and distribute
the load across the machines by assigning different thread groups or
controllers to each instance.
