Question
What is the relation between Response Time and Throughput?
 Question Submitted By :: Mahesh SV
I also faced this Question!!     Rank Answer Posted By  
 
  Re: What is the relation between Response Time and Throughput?
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.

Answer
# 2
Response Time:-The time to get first response from the
server is called Response time.

Thourhput:-The speed of Sever processing to respond to
request in one second of time is called Throughput

  Re: What is the relation between Response Time and Throughput?
Answer
# 4
response time->
Is the Sum of (Time for 1st Byte + Recieve Time)

Time for 1st Byte = The time to get first response from the
server

Recieve Time = The elapsed time b/w first response and last
response or byte of information received from the server


Throughput->
Is the average amount of data in bytes that the Vusers
received from the server in a second.

Answer
# 5
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
# 6
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

  Re: What is the relation between Response Time and Throughput?
Answer
# 7
Throughput - It is the amount of work that a computer can
do in a given time
period
Response Time - The amount of time between a single
interactive user
request being entered and receiving the application's
response is known as
response time
– “The speed with which one or a set of batch programs run
with a certain workload
or how many interactive user requests are being handled
with what
responsiveness”
– “Cost per million instructions per second (MIPS)"
provides a basis for comparing
the cost of raw computing over time or by manufacturer,
throughput theoretically
tells you how much useful work the MIPS are producing”

  Re: What is the relation between Response Time and Throughput?
Answer
# 8
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.

  Re: What is the relation between Response Time and Throughput?
Answer
# 9
Throughput= The amount of data coming from the server per
sec in bytes for the request.

Response time= The total time between client to server and
then server to client is called Response time.

Answer
# 10
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
