control pktgen rate: How to specify transmition rate?

i run this command

sudo -E /home/admin/dpdk-pktgen/pktgen2/build/app/pktgen --socket-mem 32768 -l 0-20 -n 4 --proc-type auto --log-level 7 --file-prefix pg -a 12:00.0 -- -P -m "[1:2-20].0"  -T -s 0:/traces/filename.pcap

but 20 core make no difference than with 1 core

enable 0 pcap
set 0 rate 100

It send 45 only Gbps

enable 0 pcap
start 0

it send 100 Gbps

this is my card 0000:12:00.0 'Ethernet Controller E810-C for QSFP 1592' numa_node=0 drv=vfio-pci unused=ice

why i can't control rate over 45Gbps? i would like to be able to send at 80 Gbps ?

dpdk is 24.11.0-rc0 Pktgen 24.10.3
