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 Multithreading support #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 OpenSSL 3.0 support (deprecated APIs) #1300, PR
    Bmah openssl3 #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 iperf3 authentication not working #1583, PR Validate that server authorized users file is accessible #1585).

• Developer-visible changes

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