Hello All,
I added a Windows script (Complements to StackOverflow) to JTSDK v2.0.0
\scripts directory that allows timing of commands, for example,
Need to run the update first to get the new file, then:
[1] Open JTSDK-QT
[2] cd /d WSJTX JT9.exe location
[3][ Run command using Joe's example
Hi Alessandro,
I replicated your tests as exactly as possible, modifying
CMAKE_CXX_FLAGS and General_FFLAGS by the addition of -mtune=native.
Using WSJT-X and the Shift+F6 command, the sequence of ten files
(01.wav, 02,wav, ... 10.wav) was processed in 21 seconds with or without
the addition
performance without the enhanced instructions relative to
with them.

I didn't quite realize that jt9 didn't use the dll.
What dll are you referring to? If you mean the FFTW library, jt9[.exe]
definitely *does* use it.
What's the command line to run jt9?
Type jt9 by itself at the command prompt, to get a brief usage
message. For example:
Hi Joe,
I will try other tests in next days.
Today I try the test on a desktop i7-2600 cpu@3.4GHz OS window7 64 pro
The test is on 100 files named from test00.wav to test99.wav
I modified in display.cpp the line 40 routine void
DisplayText::insertLineSpacer()
to

Hi Sandro,
Another resource for compiler / app tuning is the Gentoo. They are
constantly looking for the best safe settings and playing with advance
