most of this is in the component documentation.
http://jakarta.apache.org/jmeter/usermanual/index.html
the response time you see in JMeter is the total elapsed time. If you do not check
"retrieve all embedded resources from HTML files", it is just the html. If you check
it, it is the total time to get all the resources including html.
Remember the response times are always estimates and never use the average as "actual
response time" from a user's perspective. Since JMeter does not render the pages, the
response time is faster than the total time to transfer the data + browser rendering
time. Depending on how deeply nested the html tables are, it could take the browser
and additional 2-5 seconds to draw the page.
keep in mind network latency can greatly affect the user's perception of response
time. If someone is using a bad modem, the page will load considerly slower. I tend to
error on the side of safety and state the results are only indicators of likely
performance :)
you'd be amazed at how people will interpret the results.

Hey guys,
I was wondering how accurate is Jmeter in measuring load time. I'm working
on a report for a client and I need to know are these numbers reliable.
I've only been working on Jmeter for a few days and everything looks
promising. A few questions I would like to know is are there any hints
anyone can provide to give me the most accurate information on the load
times. Also when Jmeter is set to follow all elements in the html page like
images does it do applets too? Does it measure the complete time it takes
to download the applet or just the time it takes to send the applet? Having
this knowledge would greatly help in my efforts. Thanks for all the help!
