Axis performance reading socket input stream

           Summary: Axis performance reading socket input stream
           Product: Axis
           Version: 1.1
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Serialization/Deserialization
        AssignedTo: axis-dev@ws.apache.org
        ReportedBy: a.fernandez.martinez@ibermatica.com


Local and remote machines as SOAP client and server: PIII@800MHz, over a local
100 MBit ethernet.
A small SOAP message is sent (sequentially) a number of times. Axis was making
about 3 requests/second over a local 100 MBit ethernet. Quite insufficient for
any real-world application.

After looking for the bottleneck, the class org.apache.axis.SOAPPart seems to be
the culprit. Specifically this snippet from getAsBytes():
        // Assumes we don't need a content length 
        try { 
            InputStream  inp = null; 
            byte[]  buf = null; 
            try{ 
                inp = (InputStream) currentMessage ; 
                ByteArrayOutputStream  baos = new ByteArrayOutputStream(); 
                buf = new byte[4096]; 
                int len ; 
                while ( (len = inp.read(buf,0,4096)) != -1 ) 
                    baos.write( buf, 0, len ); 
                buf = baos.toByteArray(); 
            }finally{    
              if(inp != null && 
                currentMessage instanceof
org.apache.axis.transport.http.SocketInputStream )    
                inp.close(); 
            }  
            setCurrentForm( buf, FORM_BYTES ); 
            log.debug("Exit: SOAPPart::getAsBytes"); 
            return (byte[])currentMessage; 
        } 
        catch( Exception e ) { 
            log.error(Messages.getMessage("exception00"), e); 
        } 

Patch and test will be attached once I figure out how.
