You might remember that I made tests with the Atom boards and they didn't work as expected. Back then we came to the conclusion that different versions of the board where performing differently.
When the European Integrator's meeting were held one off the German guys told me he had a lot of experience with these kind of boards and they truly behave different. But he gave me a quick tip: Use a PS/2 mouse! So, I just reinstalled one of them with Xubuntu and the 12.04 installation and decided I should try the mouse trick. I tried both a USB and a PS/2 mouse. Hyper threading is disabled, no boot options yet and it went from 25 000 to 15 000 ns. It was actually holding a pretty stable 9 000 for a long time with xeyes, downloading files, HQ youtube clip and a Vimeo video running at the same time. Something made it jump to 15000 and then back again. Graphics still lags with this setup even though Xubuntu seems much better. I added isolcpus=1 to the boot options and did the latency test again. Ran it twice (the movies lags like crazy) and got 11400 and 9100 ns. >From 28 000 ns to 10 000. That's a difference. I'm going to run Mesa cards with these PC's so the timing isn't that critical any longer. It feels pretty nice though that the boards can behave a bit better than before with a very small fix. /Sven ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
