Syndesis-dv server has CPU resources limit value set to 750m. However the CPU request value is not set, so the request is generated to 750m as well. In that case, the Syndesis-dv server takes 750m during the idle too. For example, Syndesis server pod has the request value set to 450m:

      resources:
        limits:
          cpu: 750m
          memory: 800Mi
        requests:
          cpu: 450m
          memory: 256Mi

For example, Large instances on AWS have 2 core CPU. In that case, the OCP node has available 1500m CPU resources and the Syndesis-dv takes the half resources of the node.
