Observed unequal traffic distribution at server side

Gatling (Open-Source)
1

Hi All,

Good morning ,
Today I ran 2 Tests:
One through gatling :
Observation : Observed unequal traffic distribution at server side (1 server was serving ~20 req, second server was serving ~40 req and 3rd server was serving ~55 req)
one through Jmeter:
Observation : all Servers are serving request ~25 means equal traffic distribution

I am using Loadbalancer IP in both scenarion,
Can anyone please help what I am missing here cause of seeing unequal distribution in gatling ?

115 rps on one side, 75 rps on the other one? At such low throughput, such as difference can only be explained as totally different than injection profile (not same number of users or connections) or configuration (cookies enabled by default on Gatling while they aren’t on JMeter).

Thanks for quick reply Stéphane , but I was looking why I am seeing unequal traffic distribution at server side (1 server was serving ~20 req, second server was serving ~40 req and 3rd server was serving ~55 req), while hitting Test through gatling .
It would be great help…!!!

I understood your question correctly.

You should first try to understand how your load balancer works and how it balances traffic to the downstream servers.
