Is sshd limiting the rate of successful connections?

[Alex Kapranoff]

Good day!

It seems that a recent 5-STABLE limits the rate of successful incoming
logins. Is it true? We failed to find the relevant code neither in
openssh nor in openpam. The symptoms are that after a big number of
quick successful logins sshd starts to delay or block login attempts
for as long as 10 seconds. Does someone know anyhting about such
behaviour or is this some obscure configuration problem (read: pilot
error)?
