System performance depends on many factors, CPU speed, memory
architecture etc. Trade-off between packet size and overheads differ,
but indeed should be taken into account when deciding to offload or
not. Note that besides performance, other factors like security level
(e.g. side-channel attack resistance, key management), or functional
safety (automotive and other safety critical domains) should be
considered as well.
