Tape import slower than slow

Hi,

 

I am importing tape with LTO-4 drive adn DP 9.00. The media agent is on different server than CM connected by 1G network. The import seems to crawl at incredible slow speed, see bellow. The CPU, I/O, disk and memory doesn't show any high activity on both servers. Counting elapsed time and imported bytes and 800GB data on tape, it will take 4hours/160Mb*800*1000 = 83 days to import. Where can I look for possible clues? The tape was written yesterday and it took 110 minutes. I expect the same time to read/import the tape.

 

Kind regards, Jan
