Hello,

To make Iperf also useful with 10 Gbit/s connections, Integer
calculation should definitely be performed with 64 bit Integers. As has
been reported before, in "lib/headers.h" there should be checked if the
type "long long" could also be used for "max_size_t" and not only
"int64_t". In the versions we use, we modified "lib/headers.h" to use
"long long" when "HAVE_INT64_T" has been defined, but an autoconfig
check for that would be much more convenient.

Typical also a variable / struct element as "mUDPRate" for UDP shaping
and connected calculations should be in 64 bit Integer or Double.
Therefore, the changing of the type of "mUDPRate" from "double" in
V. 1.6.5 into "int" in "V. 1.7.0" is really no improvement. It forces us
to use still V. 1.6.5.

Would it be possible to use in the next (sub)versions of Iperf
64 bit Integer or Double calculations when required?

    Kind regards,
    Hans
