It depends on capture setup, link type, the path data is flowing etc.
TCP Dup ACKs are part of normal TCP loss recovery mechanism. You should pay close attention to them if you have performance problems.
TCP out-of-orders can be a sign of not optimal capture setup or equal cost multipath on the network.
In your trace I do not see much influence from these packets on transfer speed (look at the delta time column).
