Question
What is the relation between Response Time and Throughput?
 Question Submitted By :: Load-Runner
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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.

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
# 3
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.

Relation between Througput and Response time :

Throughput is Inversely Proportional to the response time.

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.

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

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.

Through put:- It is the total amount of work perform by the computer system over a given variation of time.

Response time:- It is define as difference of time between a user submit his job to the system for processing and the time he receives output

Hi I urgently need a substantial answer for one Q on Vusers - Performance Center. Hope you could help me. Q : My application is intended to undergo soon the load testing with performance center. The Vusers we planned are 100. But the dev team says that we should use 100 different UserID/Password's & each Virtual user should login into a different account while testing. Firstly, is this required ? my application can handle multiple logins for the same userid/password, hence is it mandatory to use 100 different account when we can do the same test with one account. If so, for 1000 Vusers we cannot use 1000 logins right ? I need substantial info to prove my point. Secondly, is this possible to assign a different userid/pwd to each Virtual user ? Thanks in advance & awating your reply Harsha Verizon 9
