Synopsis
determine_maximum_mpps [-a cpulist] [-m maxlat] [-n cycles] [-f | -r] [-p priority] [-h]
Description
determine_maximum_mpps will find the maximum mpps parameter which can sustain
1. 10 consecutive 30 second runs.
2. 1 run of 10 minutes.
Without violating the latency specified with $MAXLAT (default 20000)
Terminology
mpps : million-packets-per-second
Options
- -a cpulist
List of processors to run on. The default is processor 0
Numbers are separated by commas and may include ranges. Eg. 0,3,7-11- -m maxlat
Maximum latency in nanoseconds. The default is 20000. If the maximum is exceeded, that run of queuelat quits.
- -n cycles
Extimated number of cycles it takes to process one packet. The default is 300
- -f
Set the scheduling policy to SCHED_FIFO. This is the default if not specified.
- -r
Set the scheduling policy to SCHED_RR.
- -p priority
default priority = 1. Valid numbers are from 1 to 99
- -h
