SSHFS performance

[tasket]

Note that SSHFS creates a possible performance issue for wyng arch-deduplicate because of this (sshfs man page):

Hardlinks If the SSH server supports the hardlinks extension, SSHFS will allow you to create hardlinks. However, hardlinks will always appear as individual files when seen through an SSHFS mount, i.e. they will appear to have different inodes and an st_nlink value of 1.

If you must use SSHFS with deduplication, it is better to stick with wyng -d send.

Since Wyng also creates large directories, enabling and configuring directory caching in SSHFS should improve performance.

As a trace, this is how SSHFS was setuped in my past tests from qubes+ssh desination qube (though ~/.bashrc) sudo sshfs -o allow_other,idmap=user,StrictHostKeyChecking=no,Compression=no,kernel_cache,cache=yes,nonempty,reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,IdentityFile=/home/user/.ssh/id_rsa user@server:./ /home/user/rsync-net_mountpoint/
