Subject Re: Analyzing results: Load Time vs. Latency
Date Fri, 16 Oct 2009 20:34:36 GMT
Hi again
thanks for the link, a useful resource.

Surprisingly I found the same latency description in the glossary:
http://jakarta.apache.org/jmeter/usermanual/glossary.html

So, I've known enough about the latency and the load time 
(http://www.mail-archive.com/jmeter-user@jakarta.apache.org/msg19328.html)
