amdump -o tapetype=mytapetype
 or maybe you mean
amdump -o tapetype:LTO4:blocksize=2048

Not sure what you mean, beyond what amcheck does.

If you want to see, for absolutely sure, what blocksize it's using,
make up a fairly small backup set (trim your disklist temporarily) and
run amdump under 'strace -f -e write amdump 2>/tmp/trace' or the
equivalent for your operating system.  You should see a bunch of write
commands in /tmp/trace, and the size of the writes are the blocksize
Amanda is using.

There could be lots of other things slowing Amanda down.  Are you
doing software compression?  Are you using a holding disk?
