|Based on your suggestion, I added the following code:
| // HACK! This is to cause the SSHD not to buffer data for better
|performance
| com.jcraft.jsch.ChannelExec hackChannel = (
|com.jcraft.jsch.ChannelExec ) dataSession.getSession( ).openChannel(
|"exec" );
| hackChannel.setPty( true ); // Assign a Pseudo TTY to our Session
|to improve latency for small packets from SSHD
| hackChannel.connect( );
| hackChannel.disconnect( );
|After this code executes, any reverse forwards over this Session are
|high performance (no latency).
|I am also worried about a timing issue by disconnecting the ChannelExec
|immediately after connecting in a high-volume scenario.
|What do you think?
I have no suggestion about timing of disconnection,
but in a high-volume scenario, "hackChannel.connect()" may
fail(or throw an exception) due to timeout by network latency,
out-of-resouces on the remote, etc., so such a case should be cared for.
Sicnerely,
