Ah OK, still that looks as it is running nicely, and that is a much slower computer overal than the one i tested on, soooo that is pointing towards the graphic driver issue........hmmmm, oh well on to more testing.....just as soon as i finish this esspreso!

Some results:
Same computer 2X 2.5GHz AMD with ATI graphic card, 3GB RAM etc, ngc file with 146603 lines of code >
Ubuntu 10.04 Linuxcnc ISO, opens and runs without any problem, Linuxcnc GUI responds normaly, screen refresh OK, drawing on screen following tool path OK, computer usable with no signs of slowing down.
Ubuntu 12.04 with RTAI 3.4.9, when opening that file it becomes completely unusable, even computer overall slows down to unusable level.
Could not test Debian Wheezy as the USB it is on decided to give up the ghosts. Will do a new USB and test tomorrow.
Did not test on other machines as running on 10.04 just made it interesting.
All systems except 10.04 have Linuxcnc version 2.8, 10.04 has 2.5.4. All things point now to the new trajectory planer as it has a much biger look ahead for the gcode. If that proves to be the case, if i remeber correctly, that can be lowered, so it would be an easy solution.

I tried to test SSH control of linuxcnc but its not trivial.
I found article with step-by-step instructions but I'm not too much experienced linux user.
Can you help me with it? It looks that could be solution for now.
This is also nice, run run linuxcnc over SSH on windows machine

Finaly got to test this with Debian Wheezy iso, booted from USB stick on the same computer, same config, same everything, Linuxcnc version 2.7 and it runs nicely, no slow downs no locking the computer, no strange memmory usage, nothing, it just runs fine!!! Strange as it should have the same look ahead as 2.8.
Definitely something to inspect further.

What about hardware for test? Are you still interest?
