This workload seems more suited to a database than a filesystem. Though
surely you've already considered such, and chose not to go that route.

With high fragmentation you get lots of seeking. What model disks are
these? What is your RAID10 geometry? Are your partitions properly
aligned to that geometry, and to the drives (512n/512e)?
