- Update from version 2.0.13 to 2.0.14a - No change in rootfiles - Release notes for change:- o scaling improvements for -P, i.e. improved support for large numbers of traffic threads o major code refactoring (see doc/DESIGN_NOTES) for maintainability, extensibilty, performance, scaling, memory usage o support for full duplex traffic using --full-duplex o support for reverse traffic using --reverse o support for role-reversal character of asterisk in the transfer id o transfer id now an incrementing integer and no longer the socket id o support for TCP connect only tests with --connect-only o isochronous support compiled in by default, must use config to disable o support --isochronous for both UDP or TCP traffic to simulate video streams o use of clock_nanosleep when supported to schedule isochronous burst starts, otherwise use nanosleep delay 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 support for --trip-times with -d and -r bidirectional tests o output TCP connect times (3WHS) in connect reports o support for application level tcp connect retries via --connect-retries n o rate-limited options of -b and --fq-rate supported for unidirectional, full duplex and reverse traffic o reporter thread designed to automatically cause packet reports to aggregate - 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 fix -o or --output using freopen to redirect stdout and stderr to a file o man page updates with examples o tested with 1000's of traffic streams, WiFi, 10G and 100G
