You might also want to check your SIZE_DATA_BUFFERS & NUMBER_DATA_BUFFERS as
well as the NET_BUFFER_SZ settings.  See the other thread in this same list
for info on these.

Quick question,

I have a netbackup client that is configured to use 4 rman channels on a
sdlt tape drive , normally the filesystem backup runs about 27-30 meg
a/sec
however, 4 rman channels  only runs 4/mb sec , what gives?

I have setup the tape is slave true / and max files per set on the rman
rcv file, and some other tuning parameters, but can't seem to get the
channels to run faster than 4 /mb sec .
