Gaussian Random Timers Additive?
Hello All,
I want to know for certain if the Gaussian Timers are additive.
Example1:
Thread Group
- Timer1 (Ave 10s, deviation 1s)
- Loop1
- Sampler 1
- Loop2
- Timer2 (Ave 5s, deviation 4s)
- Sampler2
So the Sampler1 requests will an average of 10 seconds apart plus or minus 1 second (so within 9-11 seconds)
For Sampler2 I hope the requests will be 10+5 = 15 seconds apart plus or minus 1+4 = 5 seconds (so within 10-20 seconds).
Is this correct?
Example2:
Thread Group
- Loop1
- Timer1 (Ave 10s, deviation 1s)
- Sampler 1
- Loop2
- Timer2 (Ave 5s, deviation 4s)
- Sampler2
In this case the timers wont affect each other?
So Sampler1 should still be 10 +- 1 seconds, but Sampler2 should be 5 +- 4 seconds. Is this correct?
Mit freundlichen Grüßen

AW: Gaussian Random Timers Additive?

Hi Sebb,
thanks for the answer, perhaps though you could take the time to say whether my assumptions about the examples I gave are correct?

All timers behave the same - they are applied to all samplers in scope.
If there are multiple times in scope, they are all applied.

The Java Request Sampler can be used to create a simple offline test
for experimenting with timers etc.
