Hi Martin,


thank you.


I toke the debugger and could follow down in code fromm y sample through
all axis2 stuff, unless I hit


CommonsHttpTransportSender.invoke(mc)  which goes into

which goes down to Line 404

                                sender.send(mc, url, soapaction);


and this call takes then up to 4 to 10 minutes for a 25 MB file;  


So my decision: got all the open sources from asf/repo for
httpcomponents and will now build and check why
CommonsHttpTransportSender.invoke / write... / sender.send  behaves like


My I will then need some assistance. But let me see what happens in the

Trying to narrow down the environments in play here
Network Path
what happens when you run Axis client outside of NB?
If your MTOM client achieves consistent rapid results you know NB plugin
is at fault

On the other hand if you port the same Axis Client to another box
clean the arp cache and run the AxisClient repeatedly 
If you achieve consistent rapid results you know your Network path (Arp
cache?) is at fault on  box 1

If there is consistent degradation on both boxes over a period of time
the problem is with AxisClient
and or Axis Service

Apologies as this is Not an answer but a means to narrow down the

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 (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

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. ! J

But any hint where I can start to hunt this phenomena would be very

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'

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.
