lat_connect -S hostname
is a client/server program that measures interprocess
connection latencies. The benchmark times the creation and connection of an
AF_INET (aka TCP/IP) socket to a remote server. Care is take that the
connection time does not include any other overhead, such as the
or remote port lookups since these add more overhead
than the connection establishment itself.
has three forms of usage: as a server (-s), as a client
(lat_connect localhost), and as a shutdown (lat_connect -S localhost).
The reported time is in microseconds per connection. Output format is like so
TCP/IP connection cost to localhost: 1006 microseconds
