Reverse port forward channel performance

[Gearoid Murphy <gearoid.murphy@xxxxxx>]

Hi,

We've been observing poor throughput (230KB/s) on libssh channels 
generated from reverse port forwarding (ssh_forward_accept) via an 
OpenSSH server.

Conversely, when using a channel generated through a normal port 
forwarding call (ssh_channel_open_forward), we observe far greater 
throughput (8MB/s).

Has anyone observed or experienced similar issues?, is there some 
configuration aspect of the channel setup which needs to be modified?

libssh 0.5.2-1
Linux 3.0.0-15-generic x86_64 x86_64 x86_64 GNU/Linux
openssh-server 1:5.8p1

Thanks
