Patrick, I think I misunderstood you there.
There are two possible slowdowns there could be still. One is that you hit some line count where you need to reallocate the array of lines because you have too many. The other is that the search for placing the line in the correct band is slow when there are more bands to look through. The former would be just pure bad luck, so there's nothing to do about it. I would suspect the latter is your problem. You need to search through the existing bands for every new line to find where it belongs. Since bands are often clustered closely together in frequency, this could slow down the reading as you get more and more bands. A smaller frequency range means fewer bands to look through. //Richard On Sun, Sep 19, 2021, 22:39 Patrick Eriksson <patrick.eriks...@chalmers.se> wrote: > Richard, > > > It's expected to take a somewhat arbitrary time.
