JMeter on Linux Http Sampler
We are using JMeter 2.0.3. There seems to be a problem with the Http
Sampler component. The test was pretty simple, and we did the same
experiment with a tool that we have written using Apache http client.
What we did is we have written an empty jsp page and called it using
JMeter and our http client tool. We have used 40 threads and used only
one listener on the JMeter test. The throughput was around 1600/min.
The same test with the http client tool has yielded 10000/min.
The client computer was a Celeron 1.7Ghz, 1GB memory. And JVM memory
parameters were -Xms256m -Xmx256m.
What happens on the JMeter side is weird interruptions when calling the
web server.
I think I have tested it using no listeners, the same interruptions were
still there.
I never have tested it with a lower thread size.
What's might be wrong with this setup? Or is this the expected outcome?

Ramazan YILDIRIM

actually my benchmarks against tomcat for static files was using
Httpsampler2, which uses apache Httpclient. testing a blank page
really only tests the parsing of HTTP header and the OS socket
performance.
In practice, on real webpages, JMeter will do just fine.

Might be worth trying the HTTPClient HTTP Sampler, which uses the
Apache HTTPClient implementation.
Also, running non-GUI is likely to help, as far fewer resources are needed.

if you look at the static file benchmark I ran several months back,
you'll see that JMeter does have limits and doesn't handle files under
1K effectively. I haven't had time to track down the cause. For files
larger than 1K, JMeter matches the performance of apache AB. you can
see the raw results here
http://cvs.apache.org/~woolfel/tc_results.html
the article is on Tomcat's resource page.
