latency and response time

[sami.rahal at sofrecom.com]

Hello Greg
Thank you for your feedback
Latency is the amount of time it takes for a data packet to go from one place to another but
Response time it's the total time taken to respond to a service request, including the service time (time to complete the requested task) and the wait time (time spent waiting in a queue for service).
For the DNS there are benchmarking tools that give as output the latency time (resperf) and there are tools that give as output the response time (namebench) I want  know what is the diffirence for the DNS and which value is the most important.
Regars Sami

Hi Sami.
Let me ask you a question.

How would you define the terms "latency" and "response time"?

Greg

Hello In DNS benchmarking  which is more important latency or response time? for a DNS server what is the difference between the two values?
