Then I tried to = reproduce the problem on another host *with* the VLAN based setup. Same OS version, identical setup (all Ansible here) - *no* performance = issue. Everything running =E2=80=9Efast=E2=80=9C. I=E2=80=99ll try to build a reliable test scenario with reproducibly = problematic results and report back.
