thanks that worked alright.... and how it worked! 60-70mbyte/s! not
bad :) 

the only issue with this was that it stopped to transfer the large file
(13+ gbyte) after 647Mbytes. 

output:

I tried truss'ing the process, but it looks like it just thinks it is really the 
end of file and stops transferring:

any idea? 

I have executed the same commandline with "-d 5" to see more, the file got 
rather long, so I uploaded it here:
