tar + ssh传输文件

(引用)[https://serverfault.com/questions/326490/running-multiple-scp-threads-simultaneously]

I would do it like this:
tar -cf - /manyfiles | ssh dest.server 'tar -xf - -C /manyfiles'

Depending on the files you are transferring it can make sense to enable compression in the tarcommands:
tar -czf - /manyfiles | ssh dest.server 'tar -xzf - -C /manyfiles'

It may also make sense that you choose a CPU friendlier cipher for the ssh command (like arcfour):tar -cf - /manyfiles | ssh -c arcfour dest.server 'tar -xf - -C /manyfiles'

Or combine both of them, but it really depends on what your bottleneck is.
Obviously rsync will be a lot faster if you are doing incremental syncs.
