OK, have you checked the difference between the 2 transfers? The 2nd 
(slower) transfer sends "Expect: 100-continue" in the HTTP headers. A 
HTTP 1.1 server conforming to the standard must either send a matching 
response or an error.

I guess you don't have a server that keeps to this standard :-) 
(Although I think our httpd does not conform to this, either...)
