When it gets that 100 response, Jmeter would hang for a few seconds and then eventually send the request body. I see this with a 1 virtual user load but it is more apparent with higher virtual user load. I can see the jmeter client machine's CPU have activity and then suddenly drop to 0% or near 0 and stay idle for about 10 seconds or more. I used a network sniffer program and found that this happens when the web server sends the HTTP/1.1 100 Continue response back. Why is Jmeter stalling? I am using JDK 1.4.2_04 version for jmeter. The web server is IIS 5. Is there a way tell Jmeter to use HTTP/1.0 version instead since that version doesn't understand the 100 Continue.
