WSGI upload speed is .12 kb/s

[GoogleCodeExporter]

Using the latest trunk I am using the cogen.wsgi server to handle file uploads 
with this code:

          buff = StringIO()
          stalled = False
          while not stalled:
            yield environ['cogen.input'].readline() #read(1024) #readline(512)
            result = environ['cogen.wsgi'].result
            if isinstance(result, events.OperationTimeout):
              stalled = True
            elif isinstance(result, Exception):
              import traceback
              traceback.print_exception(*environ['cogen.wsgi'].exception)
            else:
              if not result:
                break
              buff.write(result)

However a 3.8 kb gzip file is taking 30 seconds to upload. py2.6 builtin epoll 
is available. Running on a debian etch 
server VPS, and my development machine (mac os x) gives the same results. I've 
tried using different read ops, ie: 
readline(512), readline(8192), read(8192), read(512), but none seem to give any 
benefit.

Can you attach a test client for this ?

I can't reproduce it - however, you must do content-length boundary checking in 
the
wsgi app like here:
