Those 10% requests failed to connect, so you didn’t even get a response.
Which version do you use? Current snapshot has some methods that let you deal with missing response.

Hi Stéphane,

I currently using version 2.0.0.m3. I was not able to upgrade to snapshot version (we are using the maven version of galing)

Do you know the root cause of thoses faillures ?
I want to know if it i my Apache serveur who does not support so many connections, or if it’is Gatling who cannot open more conenctions to the server ?
My Apache serveur stats seem ok. i can open more http connections to the serveur from the same gatling server from my browser. Can you give me pointeurs for diagnostic ?

THank’s

Don’t you have any information in the logs?
Did you tune your OS? https://github.com/excilys/gatling/wiki/Getting-Started#os-config

I will encrease the idleConnectionInPoolTimeoutInMs and let you know if there are some good news.
Thank’s
