igen, be lehet allitva az is h mennyi interraptot engedjen, illetve vannak driverek amik atvaltanak interrupt mod-bol poll modra nagy pps eseten (nemtom mlx driver is ilyen-e).

nem bugos, fix bitrate streamenkent allitsd nagyobbra
-b, --bitrate n[KM]
set target bitrate to n bits/sec (default 1 Mbit/sec for UDP,
unlimited for TCP/SCTP). If there are multiple streams (-P
flag), the throughput limit is applied separately to each
stream. You can also add a '/' and a number to the bitrate
specifier. This is called "burst mode". It will send the given
number of packets without pausing, even if that temporarily ex‐
ceeds the specified throughput limit. Setting the target bi‐
trate to 0 will disable bitrate limits (particularly useful for
UDP tests). This throughput limit is implemented internally in‐
side iperf3, and is available on all platforms. Compare with
the --fq-rate flag. This option replaces the --bandwidth flag,
which is now deprecated but (at least for now) still accepted.
