The most I've seen a single netperf *single-byte* burst-mode test do
is on the order of 350K transactions per second, and that is when
netperf is bound to a core other than the one taking interrupts from
the NIC to get some additional parallelism. In a netperf TCP_RR test,
netperf does virutally

Even if you have a test program that blasts lots of packets, that

I'm not quite sure if I'm parsing that accurately - yes, such a

Thanks for all your help.

Collision back-offs? Perhaps - on ancient, hubbed, 100BT or 10BT
networks, but virtually nowhere else :)

The dominant rate limiter is the network-- even if you have a 1Gb

Including a 14 byte Ethernet header, an NTP query/response appears to
be 80 bytes or 640 bits. The 1GbE interframe gap is allowed to be as

Not as good as would be a special ntp client, but you can generate ntp

The ntpd sources come with ntpdate; use ntpdate -q in a shell script loop to

I don't know of any such scalability-testing client software, but I
