Hey, you can count quicker that I can ;)

This is good idea, is there a way to create a command line version of 
this or similar test that can be actually timed with 'time' command?

I use a fast 32 bit CPU. I use almost exclusively wxt and confirm that 
it's rather sluggish with data files of that size. But since I mostly do 
straight , with lines, plots I just wait a second or so. Useful to know 
x11 is much faster.

I have only done 3D plots on relatively small data files. It was a bit 
slow but usable. Next time I'll use x11.

It would be interesting to see where the bottlenecks are but I think 
there is alway a significant hit when passing through an extra layer of 
software.

The first graphics plotting software I produced in Turbo Pascal wrote 
straight to video memory and was plenty fast enough on an original XT PC 
with 480kB of RAM.

The more layers of abstraction you add the slower it gets.
