- .SH NAME
- lat_connect \- measure interprocess connection latency via TCP/IP
- .SH SYNOPSIS
- .B lat_connect
- .I -s
- .sp .5
- .B lat_connect
- .I hostname
- .sp .5
- .B lat_connect
- .I -hostname
- .SH DESCRIPTION
- .B lat_connect
- 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
- \fIgethostbyname()\fP or remote port lookups since these add more overhead
- than the connection establishment itself.
- .PP
- .B lat_connect
- has three forms of usage: as a server (-s),
- as a client (lat_connect localhost),
- and as a shutdown (lat_connect -localhost).
- .SH OUTPUT
- The reported time is in microseconds per connection.
- Output format is like so
- .sp
- .ft CB
- TCP/IP connection cost to localhost: 1006 microseconds
- .ft
- .SH "SEE ALSO"
- lmbench(8), lat_unix_connect(8), socket(2), bind(2), listen(2), connect(2).
