These are the Release Notes for revision 2.2pl5 of netperf: Things changed in this release *) Improved (perhaps even usable :) support for Windows, including compilation and run on Win64. *) Fixes for MacOS X and FreeBSD Things not changed in this release *) Specifying the port number(s) for the data connection These are the Release Notes for Revision 2.2pl4 of netperf: Things changed in this release *) USE_SYSCTL available on suitable FreeBSD releases to measure CPU utilization without having to resort to -DUSE_LOOPER. *) Include Solaris 9 with the Linux sendfile path under -DHAVE_SENDFILE This still outstanding in this release *) Knowing why signals are not interrupting socket calls under OpenVMS. A quick try to use threads for timing a la Win32 worked, but also cut performance in half. Any and all assistance in this area would be most welcome. These are the Release Notes for revisoin 2.2pl3 of netperf: Things changed in this release *) I started practicing what I preach and will set SO_REUSEADDR before netserver tries to bind to its well-known port. *) Initial port to OpenVMS. This includes support for the OVMS Auxilliary server (inetd replacement). See README.ovms for more details on what is involved in compiling and running netperf under OpenVMS. *) Testname comparisons are now case insensitive. This is a side effect of OpenVMS downshifting commandlines to lowercase. I made the change and decided it was OK to keep it that way, even though for OpenVMS one _has_ to set the right defines to disable that downshifting or the command-line options will not work. For example "-H" will become "-h" which isn't quite the same thing... *) Misc fixes for nettest_ipv6.c. *) Support for sendfile() under Linux Thins I would like to have changed but did not know how or didn't have time: *) Allow netserver to run as a standalone daemon under OpenVMS *) Allow netserver to run as a standalone daemon under Windows *) Rediscover an inetd-like facility for Windows *) Figure-out how to get low-overhead, accurate, per-CPU utilization figures under OpenVMS *) Get the UDP_RR and UDP_STREAM tests to work under OpenVMS, and get the TCP_RR test to work based on time rather than transaction count. There is some bug (possibly in OpenVMS?) where the SIGALRM fires, but a socket call will not return an EINTR. Things that changed prior to this release: *) Addition of the TCP_MAERTS test - this is a TCP_STREAM test where the data flows from the netserver to the netperf rather than from the netperf to the netserver. This can be useful in those situations where netperf (netserver) is installed on a remote system, but the tester has no shell access and wishes to get performance data for the path from netserver to netperf. These are the Release Notes for the 2.2 revision of netperf: Things changed in this release *) Various and sundry bugs fixed (in theory) for platforms such as FreeBSD and Linux. If I left-out your bug fix, it was purely accidental - my mind has a very small cache, and sometimes I will "lose" email in the shuffle. *) Initial support for sendfile() on HP-UX. This test will use the sendfile() call instead of send() to send data to the remote. Netperf "lies" to netserver and calls it a TCP_STREAM test since what netserver needs to do is exactly the same. A future patch may change that and simply have netserver call the same routine for both test types. Kudos to Charles Harris for the initial prototype. *) The Fore ATM API and HiPPI tests have been dropped from the distribution. Things I would have liked to have changed, but did not have time for: *) Conversion of the source and makefile to use the GNU configure/autoconf utility to make it easier for folks to build by not having to edit makefiles... You will notice that I have started to switch from "DO_MUMBLE" to "HAVE_MUMBLE" as always - happy benchmarking, rick jones --------------------------------------------------------------------- These are the Release Notes for the 2.1pl3 revision of netperf: *) An OBOB (Off By One Bug) in netlib.c that was causing a core dump on Irix should be fixed. *) Irix systems should now be able to determine the number of CPU's present automagically (code from outside, not tested yet because I have no MP Irix systems at my disposal) *) An alpha version of a TCP_CC test has been added - this is a TCP_CRR test with out the "RR." *) The -Ae has been removed from the default makefile. If someone has a nice way to automagically generate the correct makefile for different platforms I would like to learn how. happy benchmarking, rick jones ---------------------------------------------------------------------- These are the Release Notes for the 2.1 revision of netperf: Things Changed in this release: *) The XTI (Version 2 of the spec) tests are now documented in the manual. *) The TCP_CRR (Connect Request/Response) test is now documented in the manual, including a description of how it mimics the behaviour of http (the protocol underlying the WWW). *) Support for for Windows NT 3.51 OS in the BSD Sockets tests (ok, so they are really Winsock in that case :). Other test suites may be ported as required/desired/appropriate. *) Tests for TCP and UDP, using the IPv6 extensions to BSD sockets are included in this release. They are included by adding -DUSE_IPv6 to the makefile and recompiling. *) Support for a "long long" datatype should only be required for -DUSE_PSTAT compilation which is an HP-UX only thing. The *unbundled* HP compilers from at least "HP92453-01 A.09.61 HP C Compiler" and later should have the required support. The bundled compiler may not. GCC should work - check the archives listed in the comp.sys.hp.hpux FAQ for copies. The FAQ is archived on rtfm.mit.edu under the path pub/usenet/comp.sys.hp.hpux. *) A "proper" fix for double data type alignment has been included. *) A new script is included with this release which can be used to measure aggregate TCP_RR performance (multiple, concurrent instances of the TCP_RR test). A related use of this script would be measuring MP scaling. A single-byte TCP_RR test is good for this purpose for two reasons: 1) it excercises the control/protocol paths heavily without using much in the way of data copies which may be easier to scale. 2) most systems can easily saturate cards with bandwidth, but not so easily with request/response Of course, feedback on this is most welcome. *) When measuring CPU utilization, the units for service demand have been changed from milliseconds (designated ms) of CPU per unit (KB or Transaction) to microseconds (desginated us). *) For accurate reporting of service demand, netperf needs to know the number of CPU's present on a system. On some systems (HP-UX), this is automatic. For others (All), it is necessary to add a global "-n " option to both netperf and netserver. !! IF THIS IS LEFT-OUT CPU UTILIZATION AND SERVICE DEMAND FOR !! !! MULTI-PROCESSOR SYSTEMS WILL BE WRONG. !! If you know of ways to programatically determine the number of active CPUs on a system, please let the author Rick Jones know. *) other things I've probably forgotten :) Things Not Changed in this release: *) The ancillary test suites are essentially unchanged - DLPI, HiPPI/LLA, Unix Domain, and Fore ATM API. Unless there is much interest expressed in these tests, 2.1 may be the last release in which they are included. The order of retirement would likely be Unix Domain, HiPPI/LLA, Fore ATM API, and then DLPI. Miscelaneous Comments: *) The -DUSE_LOOPER CPU utilization _seems_ to be nice and low-impact on HP-UX, Digital Unix, and IRIX. It does not yet seem to be low-impact on Solaris (I need an example of priocntl usage), AIX (setpri only works if you are root), and NT (not sure of the reason). Help with those problems would be most appreciated.
