File explorer? Network?

The same

Seems everything is programmed in VBA and not in C++ if you know what I mean.

I donated, because I hoped that more channels could speed it up. Now I have to see that it even slows down everything. Kind of weird also.

Version 9.8 still runs at higher speed. That is still slower than Filezilla. 9.8 can achieve 300MB/s, when Filezilla can make a full 400MB/s. That is why I did not recognize it earlier. But would you agree that a 100 or even a 50 is too slow? Hope that helps.

My machine is a slow outdated Intel ...

I got this impression, that previous versions were faster so I just noticed this degradation recently with the newer versions, actually after I donated. I dont say there is a correlation.

No, neither failsafefilecoppy is on nor VerifyCopiedFiles. It is just so slow now. I remember that earlier versions did not have this problem. I nearly tried all settings variations back and forth. Uninstall/reinstall, fresh setup, nothing helps.

Filezilla is just as fast as my network allows.
FFS ...

Got a very slow transmission speed on FFS 12.3 donation edition.
Transfer a 12GB file with only 1 channel 100MB/s
Transfer a 12GB file with 10 channels 50MB/s

Transfer with Filezilla 10 channels 400MB/s

All transfer protocols use sftp everything else is the same. Any explanation for that? Seems ...
