Hi,
How can I measure the performance of particular nftables
rules/chains/tables with idea to optimize the bottlenecks?
Currently, I am trying to do this by commenting/uncommenting sections
of the ruleset and running iperf3. However, this seems quite
inaccurate, inconsistent and time-consuming.

iperf3 checks only link throughput. To evaluate firewall performance you would need to generate high packet rate.

How to do that?
And how will I know how individual rules perform?

I am not aware of any software-appliances or solutions to perform per-rule firewall performance evaluation, however there are a few hardware traffic generators that are able to squeze packets on a line rate speed. As for software frameworks, you might be interested in DPDK.
