Relation between Througput and Response time :

Throughput is Inversely Proportional to the response time.

Answer / xyz

Throughput (requests per min, red) grows until CPU is
saturated and then remains constant - the CPU is operating
at max throughput. Once CPU is maxed out then response time
must increase with load. In our case it increases
predictably linearly with load. A thread-per-request system
would drop off as load increases since the CPU has to spend
more and more time context switching threads and not doing
real work.

Answer / anilkumar

Throughput is the measure of the number of messages that a
system can process in a given amount of time. In software,
throughput is usually measured in “requests / second”
or “transactions / second”.

Response time is usually measured in units of “seconds /
request” or “seconds / transaction”.

Answer / chaithanya nataraj kalidindi

Through put-
indicates the number of transactions per second an
application can handle, the amount of transactions produced
over time during a test.

Response time-
Response time is the amount of time from the moment that a
user sends a request until the time that the application
indicates that the request has completed

Answer / vamsi

Throughput is the no:of bytes downloaded from the server during a transaction, whereas response time is the time taken for a transaction to complete. Until the total bytes gets downloaded from the server, we cannot consider the transaction is completed. So throughput should be directly proportional to response time.

Suppose for a login transaction, if 10240 bytes gets downloaded from the server. User has to wait until all bytes gets downloaded to consider the transaction is completed.
With 1 user load 10240 bytes may get downloaded in 2 sec
With 100 concurrent user load it may take more than 2 sec (say 60 sec) to download same 10240 * 100 bytes.

Answer / koly toe

If the response time increase with the throughput all the time it means the system is not stable, and it should be looked at, since the whole point of performance testing is to keep the system stable although you are applying a high load.

Answer / madhu

The time in between the start and till the completion of the
job is called response time

the amount of work done in a given time is called through put.

Answer / mahesh sv

The Throughput graph shows the amount of data in bytes that
the Vusers received from the server in a second. When we
compare this with the transaction response time, we will
notice that as throughput decreased, the response time also
decreased. Similarly, the peak throughput and highest
response time would occur approximately at the same time.

Answer / tauseef.jamadar

Response time: Response time is the time from start to the
end of the execution or time from start to completion of
the task. It is also known as execution time, CPU time.

Throughput: Throughput it the total amount of work done/
completed in a given amount of time. It measures the system
performance

Answer / thatikonda shivakumar

Direct Relation B/w Response Time and Throughput Means If
Throughput increase Automatically Response time also increase

Dear Gurus, I have an interview in a company in Chicago and my latest project has the following description can anyone let me know what would be the QUESTIONS that can be asked from the following. Thanks,  Developed test cases and test plans and analyzed the test results using for LoadRunner.  Involved in Load/Performance Testing  Created LoadRunner Scenarios and Scheduled the Virtual user to generate realistic load on the server using LoadRunner.  Created and implemented Performance tests using Mercury Interactive LoadRunner.  Enhancing the scripts using Generator and performed Parameterization and Correlation to meet the requirements.  Involved in performing load and stress test on the application and server by configuring LoadRunner to simulate hundreds of virtual users and provided key metrics to the management.  Configured and Using Performance Monitor to monitor and analyze the performance of the server by generating various reports for CPU utilization, Memory Usage, load average etc.  Involved in conducting stress test and volume test against the application using LoadRunner.  Used Quality Centre to invoke the scripts and initially performed the baseline testing and organized all the scripts systematically and generated reports.  Performed regression testing for every modification in the application using Win Runner.  Involved in performance testing of server’s load and scalability by creating multiple Virtual Users by using Load Runner Virtual User Generator component.  Created detailed test status reports, performance capacity reports and graphical charts for upper management using Load Runner analysis component.  Involved in parameterization of script using VuGen in Load Runner.
