Lower than expected performance on cloudlab xl170 nodes.

[remajin]

Hi, I am running eRPC benchmark "small_rpc_tput" on cloudlab using 10 xl170 nodes. I am getting around 3.1 Mrps instead of the expected 5 Mrps.

system = Linux node3.noaman-257258.gossamer-pg0.utah.cloudlab.us 5.15.0-131-generic #141-Ubuntu SMP Fri Jan 10 21:18:28 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

config:
--test_ms 20000
--sm_verbose 0
--batch_size 3
--concurrency 60
--msg_size 32
--num_processes 10
--num_threads 1
--numa_0_ports 1
--numa_node 0

output

Can you kindly advise me on how to get the full performance? Let me know if you need further information.
