Re: how can i use random mac addresses for curl-loader tests? Current test all use a single MAC address and I need to simulate more.

Hi Malick,

I am glad for you to abandon Avalanche :)

the your request is unusual. I think the closest thing to achieve what
you need is DPDK http://www.dpdk.org/   and  MoonGen
https://github.com/emmericp/MoonGen . it appears you are doing
http/https type of test. you could randomize MAC address and ip
address in MoonGen, then "hardcode " http payload in tcp data section.

i worked on a project to   use DPDK and MoonGen to generate ~7 million
packet per second DNS  request to test most powerful F5 hardware
platform, this is enterprise level of load testing using open source
technology

don't get me wrong, I used curl-loader and love it :) but for million
connections, packet per second level of test, the bottleneck is in the
Linux kernel tcp/ip stack that curl-loader runs on.

I bought a used $300 dell poweredge R210 and i can achieve 2.5 million
http concurrent connections.
