    so can I then draw the conclusion that Spring-ws is only usable with low concurrent usage and/or small messages?

      I need to create a streaming web service. Basically I am just trying to gather whether I can use Spring-WS to do it, or do I need to use some other solution (xfire, some other?).

      You mention a different kind of SoapMessageFactory. Would it be feasible for us to implement a new implementation of SoapMessageFactory and use it for the streaming web services (and continue to use the "normal" SoapMessageFactory for the regular ones, which we also have). How easy or difficult would the implementation and configuration be?
      Have you heard of vtd-xml? It is a far more advanced option that excels in performance and memory usage at the same time...

        I thought this too until I realized that log4j was using half of that 10x. I set the MessageTracing logger to ERROR that got it to about 5x. After increasing my eden space, I decreased it to about 2.5X for a 100mb file.
