[Tomahawk-users] Trouble reproducing CPS results

[Andrey F. <fa...@re...>]

Hi everyone,

I hope someone still reads this list. We are trying to achieve the
connections per second recorded in the white paper (76,500 cps) on
page 20. We are getting only around 9865 cps.

We are using the cps script provided in qa.tgz. We had to generate
our own 1000conn.pcap trace. We generated 1000 TCP connections with
full 3-way handshakes using a Perl script that that connected to an 
apache server on a machine on the network (I have attached the tcpdump 
of that transaction and the Perl script). Is this trace proper?
Is it possible to get the trace the author utilized in the white paper?
Are we supposed to be generating full 3-way handshakes another way?

Our hardware consists of six machines with the following specs:

AMD64 4400+ CPU
2G of DDR memory
Two Intel NICs (eth0 and eth1)
One Nvidia NIC (eth2, which is the management port)

These machines are connected to GigE 48-port and 24-port Netgear
switches. The Intel NICs are one the same subnet.

We also tried to utilize one dual AMD64 machine with 12G of ram and
two Broadcom GigE adapters connected to a Dell GigE switch. Our results
were the same.

Thank you in advance for any suggestions and help.

Best regards,
Andrey Falko
