Indeed, that may be the issue. It could be going so fast that the tape drive is having to wait on the next round of data for a bit. When that happens, the tape stops, rewinds, then prepares to spin forward with the next stream so that it is written at speed, in the right place. If you send something that is broken up the streaming nature of the drive stops being efficient (used to refer to it as "polishing the heads"). Are you sending lots of small bits, or one big file? Is there any way to watch the drive and see if it has gone idle while waiting? Yes, that may mean staring at a little light for a while, but if it answers the problem, go get a pizza and a soda and a comfy lawn chair. Now, I'm terribly curious!
