If TSO is the cause, you could see whether you can disable TSO on the
loopback interface, somehow (and possibly get a reduction in
throughput as a result).


Thanks a lot. I have confirmed that this behaviour was due to TSO.
Further, TSO can be enabled and disabled using the ethtool command.
For disabling the TSO on the loopback device one needs to execute (as
a user having the required privileges).
#> ethtool -K lo tso off
