O re-implemented -U for single UDP server with minimal threading interactions O improved messaging for -tcp-congestion or -Z end to end or client and server based timestamps with -trip-times all clients will get its own sum report per a server
#Install iperf2 usg full#
O option of -full-duplex implementation uses a barrier on the client side to synchronize full duplex traffic O support for -no-connect-sync which disables transmit traffic start synchronization when -P is used, defaults to synchronized O support for -txdelay-time to insert delay between TCP three way handshake (3WHS) and data transfer O support for -txstart-time to schedule client traffic start, timestamp support microseconds, e.g. O support for little's law calculations in -trip-time outputs O support for sum only outputs with -sum-only

O support for write to read latencies (UDP and TCP) with -trip-times O support for UDP traffic only from client to server with -no-udp-fin O support for frame or burst based reporting or sampling vs time based via -i (experimental) O reporter thread designed to automatically cause packet reports to aggregate - mitigating and hopefully removing thread thrashing O rate-limited options of -b and -fq-rate supported for unidirectional, full duplex and reverse traffic O support for application level tcp connect retries via -connect-retries n O output TCP connect times (3WHS) in connect reports O support for -trip-times with -d and -r bidirectional tests O support for -trip-times indicating the client and server clocks are synchronized to an accuracy sufficient, note: consider the use of precision time protocol as well as ask your data center to provide access to a GPS disciplined reference time source O use of clock_nanosleep when supported to schedule isochronous burst starts, otherwise use nanosleep delay O support for low duty cycle traffic patterns via -burst-period and -burst-size O support -isochronous for both UDP or TCP traffic to simulate video streams O isochronous support compiled in by default, must use config to disable O support for TCP connect only tests with -connect-only O transfer id now an incrementing integer and no longer the socket id O support for role-reversal character of asterisk in the transfer id O support for reverse traffic using -reverse O support for full duplex traffic using -full-duplex

O major code refactoring (see doc/DESIGN_NOTES) for maintainability, extensibilty, performance, scaling, memory usage improved support for large numbers of traffic threads O support for low duty cycle bursts (-burst-period and -burst-size)ΔΆ.1.0 change set (as of January 5th, 2021) O fixes for -trip-times and small 64 byte packets O don't use pthread_join on the client -reverse, symptom hung client

O double free fix per memory corruption when -l is less than 244 O -P and -B src port will increment for unique quintuple O fix TCP retry regression per interval reporting O thread exit signals reporter thread condition var for timely exits of the tool O redesign of tcp retry (2.1.2 fix was incomplete) O handle and warn on failed read of tcp test flags O fix UDP server to not fatal error on EINTR, use macro O relax cli errors a bit to WARN instead of ERROR O Add support for clock sync check per -X and per -trip-times : Clock sync check (ms): RTT/Half=(0.305/0.153) OWD-send/ack/asym=(0.245/0.060/0.185) O Add support for -hide-ips (don't show the ip addresses in the report outputs) iperf -s -i 1 -e -B 0.0.0.0%eth0, will only accept/receive on the eth0 interface O Add support for bind to device on the listener, i.e. O Add support for -histograms on select with -tcp-write-prefetch O Rework recvn() and writen() for when SO_SNDTIMEO and SO_RCVTIMEO are enabled O Add support for TCP_NOTSENT_LOWAT vi -tcp-write-prefetch and select() before write()
