Variation in response time Using Jmeter
Hi,
I am using Jmeter for performance testing of one of the application. I am encountering a lot of variation in response times between LoadRunner, Rational Robot and Jmeter
Jmeter Version : Version 2.2
JDK and JRE Version :1_5_0_12
Average Response times
Jmeter:
Homepage: 11.156Sec.
Search : 22.407Sec
-------------------------------------------------------------
Rational Robot
Homepage: 6.57Sec
Search : 10.17Sec
--------------------------------------------------------------
LoadRunner:
Homepage: 6.017Sec
Search: 8.017
-------------------------------------------------------------------
u can see there is difference of 12 seconds in response time of Loadrunner and Jmeter. Help anyone help me to know why its so and how i can over come this problem.
Its Very URGENT
Thanks
Puneet

G'day
Also worth considering whether the JMeter JVM has enough memory. If it
doesn't the JVM will spend a lot of time garbage collection. The JVM does
not useful work while garbage collecting but the real time ticks away and
this will give you longer response times.
Easiest way to see if this is significant is to use the JMeter parameters to
give JMeter a lot more memory and then see if it makes any difference to the
average response time.

The test plan uses Transaction Controllers, which I think will include
the time of any additional processing, such as the Regex Extractor.
But I doubt this makes much difference.
The TCs also include downloads of stylesheets, which are the same in both
cases.
JMeter does not currently cache such repeated downloads (this is
planned as a future enhancement), but perhaps the other test tools do.
Likewise for the common javascript (only appears once in the plan, but
would beome important for loops).
What happens if you compare the raw figures for the individual pages
in the test plan?

Remember that Timers are applied to ALL samplers in scope. Make sure
it is not being applied more than once.

Hi All,
I have a thread group for which I have 10 threads looping 10 times and I have 7 samplers in the thread group. I let the requests run until completion and that takes 2 mins consistently.
Now I add a 'Constant Throughput Timer' at the same scope as my samplers to throttle the throughput to 245 requests per minute. I expect the time taken to be just under 3 mins to get through the 700 samples.
However I find that the time taken is actually more like 3.5 mins. How come?

Re: Variation in response time Using Jmeter
Posted by sebb <se...@gmail.com>.
Any error messages in jmeter.log?
Might be worth temporarily adding a View Results in Table Listener;
this will show the data sizes, as well as individual times.
What does the Summary report show for min and max, and how do these
compare with the other test tools?

Re: Variation in response time Using Jmeter

I am using HTTP Request sampler,
I am recording script through HTTP proxy server.
I am sure i am downloading same amount of data and generating same load of 1 user. I am calculating average through summary report

Are you using http: or https:?
Are you sure that you are downloading the same amount of data in each test?
Server responses may vary with the headers that are sent.
Are you sure that you are generating the same load on the server in each test?
Server response may vary if the load varies.
How are you calculating the averages?
The individual sample times shown by JMeter only include the actual
sample time, but if you are using overall elapsed times and then
dividing by the number of samples, these will be affected by
assertions, and other test elements.

Which HTTP Sampler are you using?
