Preparing for latency test:
Started glxgears No. 1, 2, 3, 4, 5
..........
Started firefox with 'https://www.youtube.com/watch?v=rqJDO3TWnac', WID
================================================================================
Command for latency test is:
su user -c "latency-histogram --bbinsize 1000 --base 25000 --sbinsize 1000 --nox 2>&1 | tee -a 1712483920.lat &"
Latency testing loop started Sun Apr 7 12:58:57 PM EEST 2024,
should end after Sun Apr 7 02:58:57 PM EEST 2024

CPU core temperatures:
Core 0: Tmin: 40.0°C, Tmax: 56.0°C, (high = +86.0°C, crit = +92.0°C)
Core 1: Tmin: 39.0°C, Tmax: 55.0°C, (high = +86.0°C, crit = +92.0°C)

Core 3: Tmin: 38.0°C, Tmax: 56.0°C, (high = +86.0°C, crit = +92.0°C)

last latency data is as follows:.
7203 s base min: -14.500 us max: 14.100 us sdev: 0.500 us
7203 s servo min: -12.500 us max: 12.700 us sdev: 0.700 us
I tried to disable SpeedStep and C-state stuff but difference is 2-3% between tests.
Pretty good for using with onboard LPT port -> LPT cable -> simple "mach3" BOBs?
Thanks.
