And at now two months later, I have prepared my final code for F-RTO patch and checked it's working for SACK enabled and disabled environments: http://people.freebsd.org/~weongyo/rfc5682/ The above links include some graphs before and after applying RFC5682 patch and a patch I prepared. If no objections I'd like to commit it into HEAD and still welcomes your opinions and reviews. If you have any concerns and questions please let me know. regards, Weongyo Jeong
