   |We are currently using JSCH for doing SFTP from a Remote Redhat Linux server
   |to a Local Redhat Linux Server.
   |The command line SFTP fetches a 100 MB File in 6 seconds, where as the Java
   |program using JSCH gets the file in 30 seconds.
   |While monitoring netstat on the remote server, we noticed that the Send-Q
   |shows a max of 32K waiting for client to read during the SFTP using JSCH,
   |but during command line SFTP it shows around 400K waiting for client to
   |read.
   |I tested my application using both release 44 and 45-rc5 and there is no
   |difference in performance .
   |It seems like JSCH is reading data at 32K chunks, do you have any
   |suggestions on how to increase the chunk size JSCH?

I'll investigate what has happened.


Sincerely,
