Hi, I got negative latency values in my last load test of a web service. I searched the web and found that this might have something to do with the jdk I use? I wonder what the problem is or how to ensure that I get correct latency in future tests? I am not allowed to use Wireshark or similar to check transmission times. The load during the tests was quite low (350 requests/minute) and none of the machines involved in the test struggled. I used 2 thread groups with one Constant Throughput Timer each, all samplers are SOAP/XML-RPC Requests. I use csv format for logging. I tried to re-run the test using different jdks and got results that differed, but had negative and 0 latency in each of the tests. I used JMeter 2.3.4 r785646 and tried with the following -Java HotSpot(TM) Server VM (build 1.5.0_16-b02, mixed mode) -BEA JRockit(R) (build R26.4.0-63_CR302700-72606-1.5.0_06-20061127-1104-linux-ia32 -Java HotSpot(TM) Server VM (build 1.5.0_06-b05, mixed mode) on a machine with CentOS release 4.7 and got negative and 0 latency for all.
I tried on a different machine using BEA WebLogic JRockit(TM) 1.4.2_08 JVM R24.5.0-61 on Red Hat Enterprise Linux ES release 4 (Nahant Update 2): here I only had 0 load time (the last value) for some requests, but no negative or 0 latency. But I am unsure if this means the latency is correct this time? I might be overlooking something obvious here, so I would be thankful for hints regarding this problem.
