Well..yeah...speed..I would expect the "decode" phase to max out CPU until
all decodes are done...hate to see idle electrons. I'm a speed freak.
It doesn't appear to use 100% CPU (of even one core). Though I'm waiting
for a really busy band to really see what it does.
One thing I'm testing is I've removed the flush from decoder.f90 as being
totally unnecessary (isn't it??) since there's a flush after the loop.

To what end? Are you concerned about decoding speed? Have you looked at
the statistics in file 'timer.out', results from the built-in execution
profiler for jt9.exe ?
