I make a simple simulation like following, but when I run it , totally the 250 user only send out 250 request in about 10min, but I expect more requests (250\*600 over 10 min) were sent out.

> **_).pause(1)_**
> 
> **_}_**  
> **_setUp(scn.users(250).ramp(20).protocolConfig(httpConf))_**  
> **_}_**

I also try to use **_during(600 seconds, “longrun”)_** instead of repeat, but get the same result

what’ wrong with my scenario? How can I load the stress?

Thanks  
Kunsou

Hi,

Your simulation looks fine (and is fine, I tested it against Google and it works as expected).

Are you sure you’re properly saving the file?  
How do you run Gatling? bundle? ide? maven? Could be a bytecode cache problem.

Thank you for your quick response!

scripts is put to the user-files\simulations\basic directory.（posted script just only change some variable names）,And I just use the gatling.bat/sh to choose the simulation;

following terminal is the result I was running under windows days before(jdk 1.6.0.45),

But today I deploy the code to a fresh gatling environment under ubuntu (gatling is downloaded from your binary build, using openjdk 1.6.0\_27), previous posted log got by this run.

I also monitoring my Ethernet adapter’s activity in the running. When all the 250 user are up, the net flow dropped to zero, It seemed that all the user just sent out request then paused forever.

Could you please tell me what you get when running this simulation?

Yes ,you are right. your scripts run 100 request, see attached the simulation.log

but when I replace the url/path in your script, run again, only get 10 request (see attached simulation\_my\_url.log)

Any thing special with my server? or the intranet?

I paste my inspection from firefox

Could you change the logging level to TRACE in logback.xml conf file, please?

And just run with 1 user (will be easier to debug).

Your suggestion is great!! : one user, 10 repeat , using my service url

Following is output: the request is cached!!  
So I just add .disableCaching to an HTTP Protocol Configuration definition. then total request is 10!

I also check the [google.fr](http://google.fr) respons head : expires=-1, which may be the difference??

I feel stupid for not noticing your Expire header.  
Until next Gatling milestone (2M4), Gatling is considering Expire header in an agressive way, treating every future date as “forever”.  
Anyway, if your response is cached with Expire, Gatling will bypass the request, just like a browser, hence your very long period with Gatling not sending any request (actually performing the pauses in your loop).

Regarding the -1 value that Google returns, it has to be handled as an invalid value (a valid Expire is a date), meaning “already expired” =\> if it was cached, flush it.

Glad you finally sorted it out!

Thank you kind help!! 🙂

I do think end user should be notified the cache concern when using the **repeat/during**.
