Let me respond simply on the issue of 3 seconds. I know the value of 3 seconds has not respected in all TCP Implementations, but this is never the less the value that was put by the IETF - for good reasons. Smaller values of RTO can and do cause interoperability problems over some Internet Paths. This issue is not new, many many years ago one major manufacturer chose a smaller initial RTO and caused major upset among people using satellite links... fortunately the implementation was soon patched, but not before it entered deployment on some web servers, where the problem persisted. I suggest a value of 3 Secs is sufficient for the General internet...
