This time includes all remote execution overhead. The csh time builtin does not
include the remote execution overhead.
This is an impartial way of comparing the response time of jobs submitted locally
or remotely, because all the load sharing overhead is included in the displayed
elapsed time.
The default is off.
connect
Syntax connect [ host_name ]
Description
lstcsh
opens a connection to a remote host when the first command is executed
remotely on that host. The same connection is used for all future remote executions on
that host.
The
connect command with no argument displays connections that are currently
open.
The
connect host_name command creates a connection to the named host. By
connecting to a host before any command is run, the response time is reduced for the
first remote command sent to that host.
lstcsh has a limited number of ports available to connect to other hosts. By default
each shell can only connect to 15 other hosts.
Examples % connect
CONNECTED WITH SERVER SHELL
hostA +
%
connect hostB
Connected to hostB
%
connect
CONNECTED WITH SERVER SHELL
hostA +
hostB -
In this example, the connect command created a connection to host hostB, but the
server shell has not started.
