Hi to all. Just an update. I set the isolcpu=1. I disabled the legacy USB support from the BIOS . I finally remove the Nvidia drivers + the NOUVEAU drivers and reboot the system. After that the latency numbers are pretty good (I mean comparing with the previous numbers) . The base thread peak is less than 18000 and the servo thread peak is less than 22000 with : - The internet browser opened and Youtube video playing ; - 3 glxgears sessions opened ; - Libreoffice Draw opened ; - File manager opened and searching files and moving windows on the screen. All this running for a couple of hours. Anyway this is not the best but should be ok.
Thans a lot for the help and support you gave me. :-) Alex On Fri, Nov 7, 2014 at 10:13 PM, alex chiosso <[email protected]> wrote: > Thank you Kirk for your detailed explanation I will try your tips. > My cpu is an Intel dual core so isolcpu=1 should be the right one . > > Alex > Il giorno 07/nov/2014 20:12, "John Alexander Stewart" <[email protected]> > ha scritto: > > Alex; >> >> I've made the isolcpu=1 modification but numbers are always pretty high >> > (60000-65000 on both threads) but more stable as I can see. >> > >> > >> How many cores?
