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
# 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

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”.

I need to perform a 4hr test run in performance center 9.0 there i need to rampup 10 users after 1 hour.

I am getting the following error when I run a HTTP/HTML protocol script in controller. It simply says Error: 27764 - “https://..... Failed”. I was given 3 solutions but none of them worked. Offered solutions are 1. Change the Http version to 1.1 in the Run time settings of the script. – Changed but still got that error. (One of our team mate) 2. Check if I am running a mix of http and https Urls – Checked and I am only using Https URLs. (SQA forum) 3. In the controller, add all the scripts to one group using the ‘Vusers’ option – Done, But still getting errors. (Client) One thing I noticed is If the servers are restarted and the logs are cleared then the probability of getting this error is minimal but as the time grows between server restart, The number of error increases. If any of you have come across this before please help me in resolving this error  1
