Increase Sync Worker Resources

Here is my configuration in the helm chart :

        - name: JOB_MAIN_CONTAINER_CPU_REQUEST
          value: "2"
        - name: JOB_MAIN_CONTAINER_CPU_LIMIT
          value: "2"
        - name: JOB_MAIN_CONTAINER_MEMORY_REQUEST
          value: 4Gi
        - name: JOB_MAIN_CONTAINER_MEMORY_LIMIT
          value: 4Gi

When I check the resources used by the pod in GKE I see

airbyte | source-hubspot-read-8-0-dyiam | main | 51.7 MiB

So maybe my question is more how can I speed up my job to reduce the processing time ?
I have way more memory available for the job (and same story for the CPU)
