Before doing the dd I issued: mt-st -f /dev/st0l setblk 65536 stsetoptions 0x8000
which was happily accepted, but it made no difference to the throughput. Looking at the server hosting the tape, the network was only running at about 37% capacity (32MB/s). Zipping the output of dd and writing to the non-compression device killed throughput (not enough CPU grunt to keep the pipeline fed :( I may need to get some new network cards that support jumbo frames!
