Memory usage of Window Managers & Widget Sets

[Dave_Linux]

Hi guys....

Appreciate any help you can give to a newbie. I have a few questions on memory usage of X-window systems. I know that I'm shooting off quite a lot of questions and that the more question I ask, the less people will reply.. but I really need some help :)

How much memory is actually used by small window managers like twm or mwm ?

By running these small window managers, will I increase performance such that the x-windows won't be running slowly. Example I can open many windows of netscape and the system won't be slow ?

Is there any drawback in chosing one widget set over the other when I'm designing a GUI. Example if I design a gui with tcl/tk vs. using motif, is using motif more memory intensive ?

What actually happens when you design an application with a specific widget set, example if i a running tom's window manager, then I call netscape, then I call an application I designed using Tcl/Tk widget set.. does the system use more memory because I'm using applications with different widget sets ?

Really appreciate any pointers or tips that you can give me. Thank you very much for your time...

Thanks,
Dave

Hi,

I don't have much answers to your questions except that, yes, using applications based on different graphic libraries will eat more memory.
Also, using several statically linked applications will take more memory.

Beware that some windows managers use more memory than one could think. I've heard that twm, despite is simplistic looks is heavier than blackbox for instance. You should actually test with top.

Top is misleading. It will show X using 20mb on my desktop, when I have run the same version other machines that only have 16mb. Something don't wash there. Top includes cache in its memory usage.
