Comment (by caeies):
I svn co the code and "played" a little bit with the code and the buffers.
I reach ~200KB/s by changing :
* the max_parallelism from 10 to 8 (SFTPv3Client.java)
* the buffer request from 2000 -> 4096 ("")
* the default connection.chunksize * by 16 ... (Preference.java)
A little bit of reading about the SFTP Protocol let me think that bigger
are the buffers, Quicker are the downloads ...
I will try to investigate a little bit more in what you call the
parallelism read ...
Regards,
Caeies.
