I did something similar yesterday using 35,000 unique domains accessed by  
mobile clients. Sending "slow\r\n\r\n" I got

     CLOSED : 3038 (8.7%)
   NON_HTTP : 20650 (59.3%)
     STATUS : 10092 (29.0%)
   SUCCESS? : 1061 (3.0%)

Where CLOSED us closing without sending any data, NON_HTTP is a response  
without HTTP headers, STATUS is a HTTP error response and SUCCESS? is a  
HTTP 200 response. I recorded the time for all the requests and got this  
for the requests that were closed without any data returned.

Close response times
  0 : 1740 57.3% 57.3%
  1 : 275 9.1% 66.3%
  2 :  28 0.9% 67.2%
  3 :  10 0.3% 67.6%
