The usage of the pool is for daily backups, with rsync. Some big files are updated simulteanously, in different FS. So, I suspect a huge fragmentation of the files ! Or maybe..., a need of more RAM ??
You forgot to tell us what brand/model of disks you are using, and the controller type.
It seems likely that one or more of your disks are barely working from time of initial installation. Even 20 MB/s is quite slow.
Use 'iostat -x 30' with an I/O load to see if one disk is much slower than the others.
