Comment (by caeies):
Ok, good to know that :)
If it can help :
* I take a look at the sftp stuff (the openssh client) and it seems
that the window adjust size is around 131072 when yours, in my last, tries
is around 16384.
* I have tested message size of 4096 -> 32768 and a chunksize of
32768*64 and max_parallelism set to 100 I've reached then ~300KB/s.
If you need more testing, let me know.
Good luck with the refactorisation of the SFTPv3Client.
regards,
Caeies.
