These are the results from running the latency test for 10 hours, with Firefox, glxgears & glxhead running in the background: Max Interval (ns) Max Jitter (ns) Servo Thread 992204 4364 Base Thread 29631 4935 CPU: Intel G530 Celeron, dual core, not HT, 2MB cache, 2.4GHz Motherboard: Asrock H61M-HVS RAM: 2x2GB sticks Video: ATI Radeon 2400 (using the default "radeon" driver, as I got better results than "fbdev") LAN: USB Wifi Bios config: OC Tweaker CPU Ratio Auto Intel SpeedStep Disabled Advanced CPU Configuration Active Processor Cores All Enhanced Halt State C1E Disabled CPU C3 State Support Disabled CPU C6 State Support Disabled Package C State Support Disabled North Bridge Configuration IGPU multimonitor Disabled South Bridge Configuration Onboard HD Audio Disabled Onboard LAN Disabled ACPI Configuration Suspend to RAM Disabled ACPI HPET Table Disabled USB Configuration Legacy USB Support UEFI Setup Only I set isolcpus=1 as a kernel option, as this is a dual core CPU: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting#The_isolcpus_Boo t_parameter I then played with onboard (oncpu?) video, and got the following (slightly worse) results after an hour: Max Interval (ns) Max Jitter (ns) Servo Thread 993478 5638 Base Thread 31612 7159 If someone could point me to how to add this to the wiki, it would be appreciated. -- Alastair D'Silva mob: 0423 762 819 twitter: evildeece msn: alast...@d-silva.org blog: http://alastair.d-silva.org ------------------------------------------------------------------------------ Ridiculously easy VDI.
