Answer / alok
Relation between Througput and Response time :
Throughput is Inversely Proportional to the response time.
| Is This Answer Correct ? | 50 Yes | 13 No |
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.
| Is This Answer Correct ? | 6 Yes | 5 No |
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

how can we test clent server application and what is the preliminary requirement for load testing
We have executed a scenario in controller from 3 diff Load Generators..How can we measure or get the response time of transactions of individual LG's....?
How do you identify the performance bottlenecks?
How do you debug a LoadRunner script?
if thoughput will be high /low what will be the problem?
Correlation without manually how u can do? i.e Automation correlation option where it is?
How can performance bottlenecks be identified?
i dnt kw loadrunner but i want kw.plz can any 1 help me
How is automated correlation configured?
here 100user and 8hours time and 500000 transactions what r the inputs nees for this scenario?
How to increase the load on Server when number of users restricted?
Hi, this is hari. I reciently joined in a small company on testing. there is no team for testing am only the person to do. i know manual testing, i have knowledge on QTP 8.2. I currently working on web based application. but in my company they want Load/Performance testing. plese tell me what i have to do?? i know Load runner but i have no real time exp on that! and In which areas i have to apply QTP??
