Strange. What happen if you increase the number of threads and use the
flow load balancing:

  - interface: eth0
    threads: 2
    cluster-id: 99
    cluster-type: cluster_flow
    defrag: yes
    use-mmap: yes

Blog fixed. Thanks for the remark. Regarding the list of runmodes, there
is some stupid typos (my fault I think) but it would break backward
compatibility if we change it now.
