mitigating and hopefully removing thread thrashing o support for frame or burst based reporting or sampling vs time based via -i [f|F] (experimental) o support for UDP traffic only from client to server with --no-udp-fin o support for write to read latencies (UDP and TCP) with --trip-times o support for sum only outputs with --sum-only o support for little's law calculations in --trip-time outputs o support for --txstart-time <epoch-time> to schedule client traffic start, timestamp support microseconds, e.g. unix $(expr $(date +%s) + 1).$(date +%N) o support for --txdelay-time to insert delay between TCP three way handshake (3WHS) and data transfer o support for --no-connect-sync which disables transmit traffic start synchronization when -P is used, defaults to synchronized o option of --full-duplex implementation uses a barrier on the client side to synchronize full duplex traffic o no limits to group sum reports, i.e. all clients will get its own sum report per a server o improved report timestamps, e.g. end to end or client and server based timestamps with --trip-times o improved settings messaging o improved messaging for --tcp-congestion or -Z o re-implemented -U for single UDP server with minimal threading interactions o re-implemented -1 or --singleclient where server will serialize traffic runs o warning message if the test were likely CPU bound instead of network i/o bound o fix the case when -P <value> is set on the server such that summing output is displayed o multicast listener will autoset -U (single server), e.g -P > 1 not supported for multicast o multicast listener no longer busy drops multicast packets during traffic test, i.e. only server thread receives them o immediate bail out on mutually exclusive command line options o getaddrinfo bug with -static linkage workaround and DNS lookup one time in setttings context vs twice in Settings and client traffic thread o fix -o or --output using freopen to redirect stdout and stderr to a file o support for --local-only which sets SO_DONTROUTE on a socket to limit traffic to local hosts (default is off) o support compile time option of --local-only to set on by default via ./configure --enable-default-localonly o support for date and time of in connect messages, e.g. [ 0] local 192.168.1.108%eth0 port 5001 connected with 192.168.1.62 port 36724 (MSS=453) (sock=5) on 2020-12-22 19:43:42 (PST) o support for feature of --permit-key and permit-key-timeout (defaults to 20 seconds.) The permit-key must match for the server to accpet the client's traffic. It also sets the transfer id. TCP only. o support for experimental feature of --near-congestion (tcp only) o man page updates with examples o tested with 1000's of traffic streams, WiFi, 10G and 100G
