Overview
This is used to wrap “struct tcp_info” as described in tcp(7) and /usr/include/linux/tcp.h. The following readers methods are defined corresponding to the “tcpi_” fields in the tcp_info struct.
In particular, the last_data_recv
field is useful for measuring the amount of time a client spent in the listen queue before accept(), but only if TCP_DEFER_ACCEPT
is used with the listen socket (it is on by default in Unicorn).
