[SOLVED]linuxcnc Latency test ambiguous results
Category: General LinuxCNC Questions
I have run various tests with different commands to check the latency but I don't know if I'm doing things correctly:
stress --cpu 4 --io 4 --vm 4 --vm-bytes 1024M --timeout 120s
[code]chrt 99 ping -i .001 10.10.10.10 -c 40000000
with stress I get good results with all the cpus at maximum usage, instead with chrt even if the cpus are not busy I see disastrous latency.
what should I do (kernel parameters, kernel recompilation)? the PC is not good for LinuxCNC?
If I don't use hardware parallel port and use NVEM, does this latency matter for operation?
my hardware:
motherboard: P8H61/USB3 R2.0
CPU: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
VGA: VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) (Driver NOUVEAU)
Controller: NVEM V5- JT
