Hi @tomaswolf , sorry to bother you with this one again, on our side we have
implemented a ChannelListener, that compute statistics around the Window
adjust, one remark:
- In the method for state changes we only get in the hint the sftp command
(SSH_MSG_CHANNEL_WINDOW_ADJUST) without the value of the window adjust... And
sometimes when I access the remoteWindow Size
(channel.getRemoteWindow().getSize()) right after it is already down to 0...
And we agree it is impossible we receive WINDOW ADJUST with a value of 0....
```
@Override
public void channelStateChanged(Channel channel, String hint) {
```
Long story short I cannot precisely confirm that the server sends huge
amount tiny Window Adjust but it looks like this.... And DEBUG logs does not
help for previous reasons, while here I am free to propagate context to
correlate my logs...
Second question is if I wanted to show that WE on client side are waiting on
the server to allocate more space on the window to send data (Meaning remote
size is 0 and we wait for server to send Window Adjust), do you have hint on
how we could do, I dug and could not find easy way...
Here we have the feeling that the few really slow transfer are due to the
server struggling to read data and for some reason send an insane amount of
small window adjust....
