i have never done this but i can try, make a wrapper function for the actual
read from the server.....
i feel that you have to go to kernel level, and whenever there is a read and
when it finishes
the difference in jiffies may give the answer. or the time clock may give you a
rough answer.
i hope you mean by 1024(1K) bytes a block transfer, go to the block driver of
the protocol which
you are using if hard-disk then ide, if some network protocol then for it
in the code this sequence might help.
++++++++++++++++++++++++++
do the read of one block
grab jiffies/time/etc on interuppt that starts the data-transfer
grab jiffies/time/etcon interuppt that stops the data-transfer
difference in jiffies
++++++++++++++++++++++++++
you can also explore /proc/net
to watch your connection to the server.
or netstat to see the connections to the server.
