Re: [Networker] Why is cloning so slow ?

It depends on how interleaved the tape is. If you've got 32 parallel
sessions, of which one is the informix backup, then the cloning will be
slow. If you've got 8 parallel sessions, you're cloning will be
noticibly faster.
I get between 5 and 25 MB/s on my SDLT220 drives.
