Hi all, I've developed a MTOM Client server apps sending up- and downloading larger files.
Doing some performance testing I toke 25 MB files and did some up and downloads routinely using dispatch and proxy approaches. The outcome was very nice, I had a java client working uploading axis2.zip (25MB) to a OpenVMS Java web service server within 5 to 8 seconds. Generating a stub in Visual Studio delivered me the same. A very performing CL/SV transfer aps, and the Vista task Manager showed close to 100% network utilization. Since a few days however, this is no longer the case for the java client, the network utilization has degraded to 1 to 2% and now the same transfer takes 4 to 5 minutes. Unacceptable. At the same time absolute no problem and close to 100% network utilization if I run my Visual Studio Test Suite of proxy based up and down load tests. If I changed something on my client side java code, that would be unintentionally. ! :-) But any hint where I can start to hunt this phenomena would be very appreciated? I am launching my java client within NetBeans 7.2.1 for debugging and testing reasons, also it the past it was working so nicely. There is maybe one point I can make: When I used the NB debugger, I could see the "MultiThreadedHttpConnectionManager" doing some cleanup 'running' forever. What makes him running? Fiddling a bit around within the debug-view, I have seen an immediate Network utilization going up to 100% when this manager was suspended for a moment. as I have no clue what has happen then or how to catch it any hints are very welcome. Any hints welcome. Regards Josef
