which performance test tool to use?

[takCoder]

Hi everyone,

I need and am trying to find a way to run reliable performance tests on my
Network nodes.

I am looking for proper BSD-Based tools, which give me  information about
my systems' throughput, latency, packet-drop and alike in the performance
test family...

Would you please share your experiences with me?
It would be really kind of you t do so; Thank you all in advance.

Best Regards,
