VERY slow performance

[victropolis]

We are experiencing very slow performance. See the example below. It takes almost 1 hour to get from 5% to 10% complete transferring only 1024 bytes at a time. Is there a way to change the buffer size?

It appears that in the JCraft implementation of Jsh, you can do something like the following:

getSession().setConfig("max_input_buffer_size", 10240000);

Is there something similar in the vngx-jsch implementation?

Thanks in advance!
