Query On Scaling Zeebe

Hi,
I’m using zeebe helm to setup environment and Now I would like to scale up. By default helm provides 3 pods for zeebe broker. Now I want to double this to check the performance. Now question comes on what should be the ration we need to maintain for zeebe gateway and elastic seach?
By default,
zeebe broker 3 pods
zeebe gateway is 2 pods
elastic search is 3 pods.

Will it become,
eebe broker 6 pods
zeebe gateway is 4 pods
elastic search is 6 pods.

???

Kindly provide your inputs here.

Thank you
