    It is sooo simple. The database is always limited by a bottleneck. Either:
    - disk I/O
    - memory
    - CPU
    - network

    Determine your bottleneck, solve it
    Determine your bottleneck, solve it
    Determine your bottleneck, solve it
    Determine your bottleneck, solve it
    Determine your bottleneck, solve it
    Determine your bottleneck, solve it
    etc etc etc...

    That's right, you're never finished
    That's right, this is true for all databases, not only DB2
