Hello Paul,

thanks for the information, that is what I need to know right now.
Just one more thing: the CPU / RAM /OS of the computer used.

73, Rik  ON7YD

Hi Rik, all,

I can send debug.txt to you directly if you need it.

I ran SlowJT9 in JT9-1 mode overnight on 630m. System is Windows 10
64 bit with a 6 core CPU at 3.2 GHz.

With 0 messages decoded the decode time runs about 0.2 to 0.25
seconds. The most messages decoded in one period was 7, that took
0.429 seconds. There were a few periods with 5 messages decoded,
times run from about 0.3 to 0.45 seconds on those.

The variability in time might depend on exactly what my system
is doing at decode time. In addition to Slow_JT9 I was running most
of the DXLab suite (Launcher, SpotCollector - which is known to
spike CPU usage when processing spots, DXKeeper, Commander,
PropView, DXView), SpotSpy, DX Atlas, two instances of HDSDR, two
instances of WSJT-X 1.91.1, four instances of Spectrum Lab, two
instance of Qlock, WSPR-X, and Firefox with three to four open tabs.
Like I said, it's a busy system. :) Oh, I forgot a few background
tasks. Well, anyway you get the idea.

I am leaning more and more toward preferring the 'original' timing
for the slow submodes, even if that means being able to decode only
one mode at a time.

73,
Paul N1BUG
