# $Id$ NETPERF CHANGES 2.4.4 (2008-03-30) - The LOC_CPU and REM_CPU tests will report their respective beliefs as to the number of CPUs present when the verbosity is set to more than one. This can be used when trying to diagnose issues with CPU utilization. - A kind soul who wishes to remain anonymous provided a patch to enable use of sendfile() on OSX. - Fix a misplaced \n in a format string of send_tcp_maerts, courtesy of Alexander Duyck. - There is an experimental global -r option which will allow one to include CPU utilization measurements, but make the decision about hitting confidence based on the result only. The test banner will reflects this when -r is used. - It is no longer necessary to specify a file with the global -F option when running a _SENDFILE test. Netperf will create a temporary file and populate it with random data and use that. If running aggregate tests it is strongly suggested one use a -F option. Otherwise, the overhead spent creating and populating the temporary file will be included in the CPU utilization calculation. - The configure script recognizes Solaris 11 and selects the correct CPU utilization mechanism - or rather it selects the same mechanism as is used in Solaris 10. Fix courtesy of Andrew Gallatin. - Convert a number of struct sockaddr_in's to struct sockaddr_storage's and add requisite casts to deal with some abort problems on Windows and perhaps other platforms as well. Kudos to Alexander Duyck. - One can now pass a value of 'x' to the global -f option to specify the units as transactions per second. This is the default for any request/response test, which is determined by there being a "double `r'" in the name - eg "RR," "rr," "Rr," or "rR." At present only the TCP_RR test actually looks for this to be set. - One can request bits/bytes per second as the primary output of a TCP_RR test by setting the global -f option to [kmgKMG] as with any of the "STREAM" tests. This converts the primary throughput metric to a bitrate (byterate) following the verbosity rules for a STREAM test. Service demand remains usec/Transaction regardless of the setting of the global -f option. A verbosity level of 2 or more will cause the TCP_RR test to report calculated average RTT latency, transaction rate, and inbound and outbound transfer rates regardless of the primary units selected with the global -f paramter. If the primary output is transactions per second, the reported inbound and outbound transfer rates will be 10^6 bits per second, otherwise, they honor the setting of the global -f option. All of this is EXPERIMENTAL and subject to change without prior notice in future versions of netperf. - Replace "break" with "break 2" in acinclude.m4 for a socklen macro - The default for the requested socket buffer size is changed from 0 to -1 to enable passing a value of 0 under Windows, which tells that stack one wishes to enable copy-avoidance. - Call fflush() on each interim result displayed in demo mode to make things happier for folks redirecting same to a file. From Dan Yost. - In theory each distinct netserver child will have a debug log with its pid appended to the name, somewhat like what appears to happen under Windows. - A new global, command-line option to netperf and netserver has been added. The -V option will cause netperf/netserver to display its version and exit.
