I am seeing incredibly poor performance when attempting to dump remotely
from one system to another (both are 3.1-stable as of about a week ago).
The command I am using is:
dump -0ab 32 -f luke:/dev/rsa0
When doing this I get a performance of less than 50KBs. This is to an
Exabyte 8505XL tape drive which is capable of at least 500KBs when not
compressing (though I am). If I, instead, pipe it through rsh to dd
like this:
dump -0ab 32 -f- / | rsh luke 'dd bs=32k of=/dev/rsa0
I get appx 500KBs (as expected). Does anybody have any ideas on what's
going on here? Should I simply give up on rdump and stick to the rsh
approach?
Thanks,
Bob
