Strace shows it keeps looping. sftp small files like /etc/hosts looks better, although still a bit slow. ssh between the same pair of hosts doesn't have problem at all.
We've no idea at all. Would anyone please help? Thanks a lot.

Strace shows it keeps looping. sftp small files like /etc/hosts looks better, although still a bit slow. ssh between the same pair of hosts doesn't have problem at all.
We've no idea at all. Would anyone please help? Thanks a lot.
