http://issues.apache.org/bugzilla/show_bug.cgi?id=40757 Summary: Web Service(SOAP) Request Response Time Product: JMeter Version: 2.2 Platform: PC OS/Version: Windows XP Status: NEW Severity: major Priority: P3 Component: Main AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I was doing load testing against XFire and AXIS (deployed on JBoss 4.0.1SP1). I used both JMeter and SOAPUI to measure response time, but the result is quite different. SOAPUI says it takes about 10ms, while JMeter think it takes 200ms. I checked the reponse, both SOAPUI and JMeter did get the right response back. Finally, I got wireshark and captured the packets on wire. And here is what I observed: when using JMETER, The HTTP request was segmented into two packets. There was a significant delay (about 200ms) between the first segment and the ACK. After the server got 2nd packet, it only took 5 ms to send a response back. After some research, I realize that JMeter is using Apache SOAP, which seems handle HTTP request by itself instead of using commons-httpclient. I am guessing the improper HTTP handling in Apache SOAP is the root cause. I know Apache SOAP is not supported anymore and you are planning to move to another SOAP stack. So hopefully my observation give you another reason to move since the whole Web Service(SOAP) sampler wont be able to provide accurate measurement at all. Let me know if you need any more information. I have the screen shot of wireshark and also the captured packets in pcap format . I dont know how to upload though.
