HA doesn't increase your performance. You need to add load balancing
capabilities to achieve a performance impact.

As for the Standard Deviation - seeing as its more than 50% of your
average, I come to believe that your application's performance may be a
bit jittery. But then, 100 samples isn't much to go by.

You should have your test run for several minutes, with a request rate
you consider sustainable by your application. If you have data of real
life usage peaks of your application, you may want to use the peak
access rate.

HTH,
Felix

None of them, you can't get this metric in JMeter, only request response
time.

Std. deviation is a mathematical calculation, it has no normal value. But if
you're not setting any kind of defined pacing or regulating throughput
according to requirements then you'd possibly see something like this.

Is it the Average and Max that I should decrease. or only monitoring
the throughput will do it.

Much, much, more context required.

Measure execution time of a website

2011-06-20 Thread shiplu
Hello,

I am using jmeter for my jsp website.
One of the test here is to measure time it takes to load a website,
submit a form and full result is loaded in browser.  I can simulate
the test with jmeter.  The result is following.

# Samples 100
Average 785
Min 48
Max 1397
Std. Dev. 437.63
Error 0%
Throughput 45.6/sec
KB/sec 1661.85
Avg. Bytes 37302.0

Could you tell me which value is representing the time duration I require?
I think its Average.  But Std.Dev. is too high that it seems the
result is not okay.
Do you think such high Std. Dev. is normal?

The server and jmeter is on two different machine.
