Stop logging Gatling Requests - maven

Question

I'm monitoring many web pages (around 4000), whose URLs are fed by a CSV file in the same Gatling test.
The problem is the test lasts forever. I suppose (but it may not be true) that the logging activity takes a long time. So I want to stop having the huge table with
---- Requests ------------------------------------------------------------------
> Whatever
> Blah blah blah
> And so on
---- Errors --------------------------------------------------------------------
> You got it
... only to see if it makes my test last a bit shorter.
How should I do?
I tried editing my logback-test.xml file but the logs show even with the ERROR level.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%-5level] %logger{15} - %msg%n%rEx</pattern>
<immediateFlush>true</immediateFlush>
</encoder>
</appender>
<!-- Uncomment for logging ALL HTTP request and responses -->
<!-- <logger name="io.gatling.http.ahc" level="TRACE" /> -->
<!-- <logger name="io.gatling.http.response" level="TRACE" /> -->
<!-- Uncomment for logging ONLY FAILED HTTP request and responses -->
<!-- <logger name="io.gatling.http.ahc" level="DEBUG" /> -->
<!-- <logger name="io.gatling.http.response" level="DEBUG" /> -->
<root level="ERROR">
<appender-ref ref="CONSOLE" />
</root>
</configuration>
Also, for all purposes, here is my pom.xml:

Thanks in advance for your help.

Answer 1

My question was answer on Gatling issues section; this can be configured in gatling.conf file (in test/resources).
Instead of having:
gatling {
data {
writers = [console, file]
}
}
You can have:
gatling {
data {
writers = [file]
}
}
And now your console is clear.
Have a look at this if you need to know more about gatling.conf file default values.
