Response Time of Http Request
I've just started using JMeter 2.3.2. I created a "Thread Group", added "HTTP
Request Sampler" and "View Results Tree" for my testing.
For calculation of "Response Time" of a request, is it correct to say it's
the "Load time" minus "Latency"?
I can't find the Start Time and End Time! Do they exist in JMeter?
Help!

Where is this "load time" saved in JMeter for every request?

No, Load Time is the same as Response Time and overall Elapsed time.

The default Time Stamp is start time; end time = start + elapsed.

Re: Response Time of Http Request

Are the times still 10000-20000 with one thread?
If not, then that may indicate:
1. High network delays
2. Possible Resource Contention in your server due to multi-threading, etc.
Use tcpdump or some other network analysis tool to confirm the times are high. You should be able to deduce where the discrepancy is coming from

Subject: Re: Response Time of Http Request
In the Sampler result, I don't know why the "Load time" and "Latency" are
often over 10000 and sometimes over 20000, but the actual time per request
should be 2-4 seconds if run in browser.
My "Thread Properties":
Number of Threads (users): 5
Ramp-Up Period (in seconds): 0
Loop Count: 1
If "Load time" is divided by "Number of Threads", then I think the result is
reasonable. Did I set something wrong?

Unless the test plan contains a loop controller or lots of samples, a
Thread Group loop count of 1 is not going to reach steady state.

Not sure why you would want to divide load time by thread count - what
does that show?

What do you mean "started randomly"?
AFAIK, for the HTTP Sampler the load time is the time taken to establish a
connection (retrying if necessary), send the request and receive the entire
response.
How do you define "Waiting Time"? If you mean delays caused by saturated
networks and/or processing time on the server side, there's no way to measure
that independently; it's included both the load and latency time.
> Also, I found the "Load time" is very similar to the "Latency"!
I've found that in most cases latency is equal to load time, because my
product sends back small response payloads, which are received by JMeter as
the one and only response packet for the request send.
If in doubt, use Wireshark / tcpdump to sniff the network data. You'll be able
to see from the timestamps in the wireshark dump when packets were sent

Re: Response Time of Http Request
Posted by linuxos <li...@gmail.com>.
I don't know why the HTTP Request Samples are started randomly. So, I guess
waiting time is included in the "Load time" or "Latency", and I can't
calculate the actual time used between the request and response.
Also, I found the "Load time" is very similar to the "Latency"!
Any suggestion?

Re: Response Time of Http Request
Posted by Noel O'Brien <no...@newbay.com>.
Latency is the time taken until the first response is received by JMeter. Load
time is the total time to complete the request/response.
Quoting sebb from a previous mail thread where I had a similar question:
"Latency is time to first response.
This may be the entire response, especially for small payloads."

Noel

RE: Response Time of Http Request
Posted by "Kannan, Sengamalam" <Se...@AIG.COM>.
Response time for a HTTP request = Load Time - Elapsed time
Is this correct? Or is Load time and Response time are the same?
Thanks & Regards

Re: Response Time of Http Request
Posted by linuxos <li...@gmail.com>.
Thanks. But I can't find the Elapsed time in the "Sampler result".
Here is my result from the "View Results Tree":
Thread Name: Thread Group 1-1
Sample Start: 2009-04-22 14:54:01 CST
Load time: 1489
Latency: 1360
Size in bytes: 81648
Sample Count: 1
Error Count: 0
Response code: 200
Response message: OK
Is there any wrong step in using the JMeter?

No, Load Time is the same as Response Time and overall Elapsed time.

The default Time Stamp is start time; end time = start + elapsed.
