Thanks for your responses, but what I want to do with the transfer time
information (which I hope can be known from tcp_get_info) is to give priority
to the request of the fastest connection first (which can be calculated with
size of file/transfer time). I use Apache code to give the priority but I need
information about the connection to do that. Or you can give/advice me
something/part in Apache that provide the transfer time of A PACKET THAT JUST
SENT? I will really happy to know that. Thank you very much

I just tried it with a bit of ajaxy/javascript on a keep alive
connection - but did not get very far - no convergence -- but that may
be as the CGI is not called with predictable enough a delay -- a
module may be indeed what is needed.
