Potrebbe centrare l'uso dell'algoritmo di Nagle (RFC896):

<< The solution used there was to impose a limit on the count of
datagrams generated per unit time. This limit was enforced by delaying
transmission of small packets until a short (200-500ms) time had
elapsed, in hope that another character or two would become available
for addition to the same packet before the timer ran out. >>

Potrei dire una boiata, ma mi sembra di ricordare che OpenSSH
disabiliti Nagle di default, telnet no.
