Requests process much longer after migration fron 2.3.0 to 3.0.3

Have migrated to gatling 3.0.3 on sbt. Noticed that requests that ususally took on average 500ms to process now taking 10 seconds.

For comparison reasons setup 2 identical projects with simple POST request on 2.3.0 it takes 500 ms to send request and receive response on 3.0.3 10-11 seconds.

Please advice what am I missing?

Impossible to tell without getting our hands on a reproducer.

Hello Stéphane!
Thank you for such a prompt response.
Here is a 3.0.3 example:

Please inform what numbers do you have.

$ java -version
openjdk version “1.8.0_202”
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_202-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.202-b08, mixed mode)

$ uname -a
Darwin Stephanes-MacBook-Pro.local 17.7.0 Darwin Kernel Version 17.7.0: Thu Jun 21 22:53:14 PDT 2018; root:xnu-4570.71.2~1/RELEASE_X86_64 x86_64

Pretty decent numbers here, response time is ~20ms.

Thank you.

Looks like something on my side.
Do you have any pointer what could I check in the first place?

java version “1.8.0_181”
Java™ SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot™ 64-Bit Server VM (build 25.181-b13, mixed mode)


I found another thing.
Such long request processing relates only to first “action” second goes with normal timing:

And I didn’t see any messages regarding warmup start/end unlike the 2.3.0 version.
