This utility notably decreases the startup time of your X sessions, provided
|
|
that you start a number of X clients automatically during the X session startup.
|
|
Most people, for instance, start X clients like xterm, xclock, xconsole and
|
|
xosview from their .xinitrc, .openwin-init, .xtoolplaces or .xsession file.
|
|
|
|
These X clients are started simultaneously (in the background) which puts a
|
|
high load on the X server and the OS:
|
|
|
|
* The X server is not multi-threaded, so all X clients are competing to get
|
|
access to the X server and to use its resources, which causes a lot of
|
|
overhead (= delay).
|
|
|
|
* The performance of other (non X related) tasks served by the system degrades
|
|
badly due to the high load.
|
|
If the system has not enough RAM to hold all the X clients, it is swapping
|
|
heavily, resulting again in a lot of delay.
|
|
|
|
On the Sun platform there is a utility called 'toolwait' which solves these
|
|
problems: it starts one X client in the background, waits until it has mapped
|
|
a window and then exits.
|
|
|
|
Xtoolwait is a free implementation of exactly the same idea.
