SYNOPSIS
latency-histogram [-?|--help] [--base ns] [--servo ns] [--bbinsize ns] [--sbinsize ns] [--bbins ns] [--sbins ns] [--logscale 0|1] [--text note] [--show] [--nobase] [--verbose] [--nox]
DESCRIPTION
The latency test is important when configuring a LinuxCNC system. An adjunct to the standard latency-test latency-histogram plots the distribution of latency. This can be useful to get a feel for how frequent the high latency excursions are.
LinuxCNC y HAL no deberían estar ejecutándose; deténgalos con halrun -U. Una gran cantidad de contenedores y/o tamaños de contenedor pequeños ralentizarán las actualizaciones. Para un solo hilo, especifique --nobase (y opciones para el hilo servo). Las latencias medidas fuera del rango +/- bin se informan con barras finales especiales. Use --show para mostrar el conteo en pines [pos|neg] fuera del gráfico.
