hello,
I'm doing some benchmark on Web service's Call and I have some strange results.
First of all,
My web service is on a Axis2 1.5.1 framework,
I use a Apache Tomcat 6.0.20 / JRE (server mode) 1.6.0_20-b02.
I use JMeter 2.3.4 to do my benchmark.
When I analyze my result, I have some nice (and stable ) things but some times
I observe a huge decrease of Hit/second and a huge increase of response time.
For example, normal response time is (avg) 300 ms and it increase to 1.000 ms
and more, at the same time the hit/second decrease from 90 to 40.
I watch the CPU activity to see if the bottleneck is here and I observe that I
have the same thing.
When the response time increase, the CPU activity fall down from 40% to 10%.
I watch disk time access too and I don't observe a link between this activity
and the fall of performance.
I try to attach my graph to this mail but I don't know if it's okay on the
mailing list.
I don't understand why some time the performance fall down.
So, if you are some ideas...
