Hello,

having the above card running, but can only get between 5 to 7 Gbits/sec with 
iperf3.
ixgbe card gives up to 9Gbits/sec with iperf3.

Already changed /kernel/drv/mlxcx.conf 
# The default for devices with a maximum supported speed above 10Gb/s
cq_size_shift = 12;
# The defaults for devices with a maximum supported speed above 10Gb/s
sq_size_shift = 13;
rq_size_shift = 12;

Also changed:
tcp   max_buf 4194304
tcp   recv_buf 1048576
tcp   send_buf 1048576

Latest Firmware 22.35.2000 from 24.11.2022 is installed.
Same Card in FreeBSD and Linux I get up to 26 Gbits/sec with iperf3 and no 
settings changed.

Any advice is much appreciated.

Best

_isi_
