Hi all,
Here's an updated table summarizing decoding results from the same set
of 10,682 files that I used in tests of the decoders before.
Columns labeled "JT9" and "JT65" give the number of decoded signals in
each mode. "Time" is the time in seconds to process the full data set,
as measured by calls to timer in jt9b. Columns labeles "Factor" give
the improvement ratio for each decoder, relative to v1.3 r3673.
Program Version JT9 Factor JT65 Factor Time Factor
----------------------------------------------------------
v1.3 r3673 7691 1.000 40831 1.000 14061 1.00
v1.4.0-rc2 r4400 7693 1.000 41796 1.024 13320 1.06
v1.5.0 r4926 7632 0.992 43164 1.057 6644 2.12
v1.5.0 r4950 7632 0.992 43166 1.057 5454 2.58
v1.5.0 r4955 7594 0.987 43948 1.076 4911 2.86
v1.5.0 r4955 OMP 7594 0.987 43946 1.076 4090 3.43
v1.5.0 r4998 7886 1.025 43946 1.076 4068 3.46
For what it's worth: I'm also playing with an entirely new JT9 decoder
that is faster still, but not yet as good. I will report further, if it
comes to anything.
