* per-thread CPU usage (only those threads where the load is over 0.5%, if the sum of threads below that threshold exceeds 0.5%, it prints an aggregate for those threads); * also report RSS; * network load (only on request, as percentage of specified network bandwidth and actual bytes in/out, with the output suppressed if it is 0%); * publish CPU usage so a ddsperf instance can display CPU loads for its peers; * handle SIGXFSZ (file size exceeded) by displaying one last line of statistics before killing itself; this simply a debugging tool to make it easier to get a trace covering a high sample-rate start-up issue; * default topic changed to "KS" because that allows all the options to be used, this has a negative impact on performance (both latency and small-sample throughput) but it should be less surprising to users; * specifying a size is now done by appending "size N" (where N is the size in bytes) after a "ping" or "pub" command, rather than it having to set it via a command-line option; Note that some of this is platform-dependent -- SIGXFSZ is currently only on Linux and macOS, and CPU and network load reporting is currently only on Linux, macOS and Windows.
