a5621dd908 Added zerocopy stuff to the API, so that bwctl can use it. 2013-03-06 07:46:28 -08:00

c57e9f2494 Slight change to net.c routines to better handle writes/sendfiles 
to a full socket.

987b432316 A bunch of changes mixed together in this commit, but the significant 
one is the new -Z flag.

- Fixed potential bug in net.c's Nread and Nwrite routines.  If they
had ever needed to loop they would have read/written the wrong address,
due to incorrect pointer arithmetic - sizeof(void) is not 1.  Fix
was to change the type of the buffer pointer to char*, which also
meant adding casts to some callers.

- Better checking for conflicts between command-line flags - now they
should no longer be order-dependent.

- Added a new -Z / --zerocopy flag, to use a "zero copy" method of
sending data, such as sendfile(2) instead of the usual write(2).

- Renumbered error enum to make inserting new ones easier.

358985eb58 Page-align the read/write buffer. Unclear if this helps, but 
it certainly doesn't hurt.

0da578e79f Improved version of setnonblocking() - still not used. 2013-02-28 11:26:51 -08:00

1133dd0b6c Fix long help message to show theactual default values from the .h file. 
Correct the default test duration to ten seconds.

50a45ea47e Add get/set json_output to the API. 2013-02-26 15:54:29 -08:00
Jef Poskanzer
43929b3698 Added "burst mode" to send a bunch of packets in a row without 
intervening select() calls.  This increases performance quite a bit.

Jef Poskanzer
231c56296e Comment out the "__attribute__((hot))" declarations because they cause 
compiler warnings on older systems.  They probably didn't help
performance anyway. They'll remain in the source as markers.

3a34e7c11b With the define corrected to long-long, no longer need an explicit cast 
in the tmr_create calls.

e232c5d16e Couple of defines that should be long-longs. 2013-02-18 10:28:17 -08:00

037c0c2367 Handle timers longer than 2147 seconds (2^31 microseconds). 2013-02-18 09:06:50 -08:00
Jef Poskanzer
ba55284d44 Added some "hot" attributes to mark a few routines that deserve 
extra optimization.  Most likely this has no effect.

fbaa2467a6 Change the meaning of the combination of -n and -P flags. 
Previously, if you used -n to specify a test sending a specified number
of bytes and -P to send multiple streams in parallel, iperf3 would send
that many bytes on each stream.  With this change it just sends the
specified total number of bytes regardless of how many streams are used.

eb0206e686 Better handling of non-exit errors in JSON. 
Also converted one more error to the unified call.

5a561d9d40 Get rid of commented-out obsolete code. If it's needed it's in the 
revision history.

9bfb54c0cc Add -J flag to produce JSON output instead. 2013-02-01 11:42:35 -08:00

17666b94d9 Updated the man page and help string so they correspond with the code. 
This entailed some re-ordering, so the diff is large.

2efc602fb2 The units handling was interpreting capital K/M/G as 1024/1048576/1073741824 
and lowercase k/m/g as 1000/1000000/1000000000.  This was deemed to be
too confusing.  Now both capital and lowercase give the powers-of-two version.

1f4b249abb Better fix for the -u/-l argument parsing mixup. This one avoids 
the problem of explicitly setting the UDP block size to the TCP default
and getting ignored.
 2013-01-28 14:19:07 -08:00
Jef Poskanzer
1ac282ccdd Raise default UDP block size, for better performance. 2013-01-28 14:04:39 -08:00
Jef Poskanzer
45080fc6b7 Fixed little glitch in argument handling order: "-l nnn -u" was 
setting the block size back to the UDP default, while "-u -l nnn"
worked.  Now both orders work.

6177a7f1f1 Get rid of extra select() calls before reading and writing, 
in both client and server.  Instead we pass in and use the
fdsets from the main loop's select().

874856ab6b Show retransmit count for FreeBSD too. This may not actually 
be implemented by the OS yet - the struct member starting with
a double underscore indicates that it's not fully implemented.
