I would expect no difference for small file performance between rsync and
ssh-rsync. The ssh overhead on a modern system limits data rate to something
like 75MB/s, nearly saturating a gigabit link. It seems you have basic
filesystem performance issues. More RAM, larger caches, SSD? investigate with
iostat on client or server?
