I"m having very poor performance on a Sun Ultra 60
with Solaris 9 and NBU 5.0GA.  I've added the
following files to the system with the asociated
values:

NET_BUFFER_SIZE = 65536
NUMBER_DATA_BUFFERS = 32
SIZE_DATA_BUFFERS = 262144

My /etc/system has these parameters:

set shmsys:shminfo_shmmax=33554432
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=512
set shmsys:shminfo_shmseg=100
set msgsys:msginfo_msgmap=512
set msgsys:msginfo_msgmnb=65536
set msgsys:msginfo_msgmni=1024
set msgsys:msginfo_msgmax=8192
set msgsys:msginfo_msgssz=32
set msgsys:msginfo_msgseg=8192
set msgsys:msginfo_msgtql=1024
set semsys:seminfo_semmap=64
set semsys:seminfo_semmni=2048
set semsys:seminfo_semopm=128
set semsys:seminfo_semmsl=300
set semsys:seminfo_semmns=2048
set semsys:seminfo_semmnu=1024
set semsys:seminfo_semume=64

So, why am I only getting a backup that starts at only
2000 KB/sec and then slows town to 300 KB/sec?  It may
be an obvious answer, but I can't see it.

Thanks for the help!
