[vox-tech] Need X Windows performance monitoring help

[Eric Nelson <en77@attMAPSbi.com>]

We are developing an embedded system which uses Java and X Windows.  
It doesn't have a VGA.

When we run some code on a desktop with lots of ram and vga, we get 
pretty good performance, but on our embedded system, performance is 
poor.

There are several factors which may contribute to this problem: 
swapping of the libraries or X Server itself, latency in the X 
Server, processor speed, Java, the video driver, etc.  So maybe we 
need more ram, or a faster video driver, or to lock X into ram, or 
simply go to a faster clock.

My question is, how can we time stamp events, or get a trace of memory 
and swap usage, or whatever necessary, to pin down where the problem 
is?
