SET COMMANDTIMING

Displays how much time each command takes to execute.

SET COMMANDTIMING ON|OFF

The COMMANDTIMING option is set OFF by default.

The SET COMMANDTIMING command controls the output of command timing messages.

In UNIX, the format of command timing messages is

source, line, IU|RU, user ticks, elapsed user ticks, IS|RS, system ticks, elapsed system ticks

source	The name of the application document that contains the command; if it is the ZIM prompt, source is “”.
line	The line number of the line in the application document on which the command begin; if the value of source is “”, the value of line is a sequential number from the prompt.
IU\|RU	Can be IU (interpretive user execution) RU (runtime user execution)
user ticks	The time it took to interpret the command (for interpretive execution) or the time it took to accept the command for processing (for compiled execution).
elapsed user ticks	The time it took to interpret the command, as seen by the user.
IS\|RS	Can be IS (interpretive user execution) RS (runtime user execution)
system ticks	The system ticks used by the command. Usually, the system ticks value is lower than the user ticks value.
elapsed system ticks	The number of ticks spent by the execution of the command as seen by the system. Usually the elapsed system ticks value is lower than the elapsed user ticks value.

For Windows systems, the format of command timing messages is

source, line, I|R, user ticks, elapsed user ticks

source	The name of the application document that contains the command; if it is the ZIM prompt, source is “”.
line	The line number of the line in the application document on which the command begin; if the value of source is “”, the value of line is a sequential number from the prompt.
I\|R	Can be I (interpretive user execution) R (runtime user execution)
user ticks	The time it took to interpret the command (for interpretive execution) or the time it took to accept the command for processing (for compiled execution).
elapsed user ticks	The time it took to interpret the command, as seen by the user.
