Can Iperf measure number of packet losses occurred during transmission ?


Yes, but only for UDP streams.

If you are interested in TCP, since TCP is reliable, iperf has
no visibility into losses.  You might do a search on
web100 for one way (if you have a Linux platform) to infer
whether TCP is experiencing packet loss.  I believe there even
may be a version of iperf somewhere that queries web100 variables
to show TCP state during a transfer.
