Interesting. The processor is an Intel Celeron 433 Mhz. RAM is only 256 megs (I have to allocate 2 to the onboard video). When I run the latency test over a remote X11 connection I get significantly better scores (and the UI is much more responsive) than when using the local display but I still get occasional realtime errors and latency overruns.
Aside from the latency issues the machine is quite slow. For instance running the image2gcode python script is very slow, and Axis is sluggish even over X11. I can run image2gcode on my Powerbook, and I may try a less demanding UI than Axis, but there's no point in trying if I can't resolve the latency issues. BTW: When I use a remote X11 session I disable ssh tunnelling (this produces a huge speedup). I think I've disabled any power management options in the BIOS, but I'm not very familiar with playing around with PC BIOS, so I'm not sure if I got everything. I do have USB enabled so I can use a USB keyboard to configure the BIOS. - Pat On 18-Jan-08, at 3:15 PM, Colin MacKenzie wrote: > If you have the machine in regular text mode the video card is not > the bottleneck.
