Maybe your program is "X intensive"...
As another possibility, the program may be memory demanding. Anything that induces substantial amounts of swapping will slow down X (and everything else too -- using a console won't be much better). You can use ``ps aux'' to find out about the memory hunger of your processes -- look at the %MEM column for a general overview and check the RSS and VSZ columns. A process with a size exceeding the amount of physical RAM (check /proc/meminfo) on the system usually means a noticeable slowdown (the amount of perceived and of real slowdown hugely depends on the process' memory access patterns, though). > >Antonio > > > >Marc Br?nink wrote: > >>Hi, > >>if I put my 500 Mhz machine under heavy load, X doesn't respond > >>anymore.
