LAT_CONNECT(8) LMBENCH LAT_CONNECT(8) NAME lat_connect - measure interprocess connection latency via TCP/IP SYNOPSIS lat_connect -s lat_connect [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ] hostname lat_connect -S hostname DESCRIPTION lat_connect is a client/server program that measures interprocess connec- tion 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 con- nection time does not include any other overhead, such as the gethostby- name() or remote port lookups since these add more overhead than the con- nection establishment itself. lat_connect has three forms of usage: as a server (-s), as a client (lat_connect localhost), and as a shutdown (lat_connect -S localhost). OUTPUT The reported time is in microseconds per connection. Output format is like so TCP/IP connection cost to localhost: 1006 microseconds SEE ALSO lmbench(8).
