UDP latency via Sockperf with Mellanox CX354a

I test UDP latency via Sockperf with Mellanox CX354a percentile 99.999 is 1.577 and the test result is unstable.

I found UDP latency result percentile 99.999 is 1.411 via sockperf with Mellanox CX354A release by Supermicro

Does someone have any suggestion to optimize of UDP latency??

My test conuration as below.

Run command:

Server:

LD_PRELOAD=libvma.so VMA_SPEC=latency VMA_THREAD_MODE=0 VMA_INTERNAL_THREAD_AFFINITY=2 VMA_RX_POLL=-1 numactl --cpunodebind=0 --membind=0 taskset -c 1 sockperf server -i 192.168.1.1 --dontwarmup --mc-loopback-enable

Client:

for i in seq 1 100; do LD_PRELOAD=libvma.so VMA_SPEC=latency VMA_THREAD_MODE=0 VMA_INTERNAL_THREAD_AFFINITY=2 VMA_RX_POLL=-1 numactl --cpunodebind=0 --membind=0 taskset -c 1 sockperf ping-pong -i 192.168.1.1 --mps=600000 -m 64 -t 2 --buffer-size=212992 --lls=1 --no-rdtsc --dontwarmup; sleep 5 ; done
