I have observed that the (read and write) performance of my 8mm Exabyte tape drives on my -current system runs roughly half of what it is on my 2.1-stable systems (100kb/sec vs. 200kb/sec). This is with both the NCR 810 and Adaptec 2940 adapters and using programs such as dump, tar, dd, team. The systems that I have compared have roughly the same hardware (both are 100MHz Pentiums). Performance on my Wangtek QIC-525 tape drive is about the same. Can anybody offer up an explaination of why this is and what might be done to fix it? Thanks, -- Bob Willcox bob@luke.pmr.com Austin, TX
