[dns-operations] Load testing

[Stephan Lagerholm]

Hi Miguel,

 

If you are testing a caching server, then use resperf and not dnsperf. Make sure to have a fast machine that you run from. The 3 million sample is not that very accurate. Servfails and Nxdomains are overrepresented. The mix between cache hit/misses are not evenly distributed in the file either. So you can't really draw any intelligent conclusions from that file.

 

I recommend that you create your own file based on your exact traffic. Can you for example do tcpdump and then create a little script to make a query file. I have query files if you need, feel free to reach out to me off list and I will provide them to you.

 

Thanks /Stephan

Hello

What is a good tool to load test a dns server?

I'm currently using dnsperf. I ran the 3 million sample data

But maybe dnsperf is already old and there are more tools out there that you guys are using.

Regards!
