iperf-3.16 2023-11-30

• Notable user-visible changes

  • Multiple test streams started with -P/--parallel will now be
    serviced by different threads. This allows iperf3 to take
    advantage of multiple CPU cores on modern processors, and will
    generally result in significant throughput increases (PR #1591).

  • OpenSSL 3 is now detected at build time. If OpenSSL 3 is found,
    various older, deprecated, APIs will not be used. iperf3 will
    continue to work with OpenSSL 1.1.1. OpenSSL is used as a part
    of the iperf3 authentication functionality (Issue #1300, PR
    #1589).

  • The authorized users file used by the authentication functionality
    is now checked for accessibility much earlier during the program
    startup, as opposed to being checked near the start of a
    test (Issue #1583, PR #1585).

• Developer-visible changes

  • BREAKING CHANGE: iperf3 now requires pthreads and C atomic
    variables to compile and run.
