Folks,
I have a Sun Fire 3800, with Solaris 8 OS and attached to an
Hitachi SAN.  This is a Oracle Financial DB Server.
The average data to be backed up is 168 Gigs.

Problem:
It takes between 33 and 38 hours to backup the 168 Gigs,
168243872 Kbytes at 1222.017 Kbytes/sec
There are a lot of 1 Gig files, and quite a few of them take
awhile to be backed up.  Some even take a few hours to
be backed up.

Does anyone have an idea as to what I am missing?


Solution attempts:
1. Added below to /etc/sytem, then rebooted.
* Message queues
set msgsys:msginfo_msgmap=512
set msgsys:msginfo_msgmax=8192
set msgsys:msginfo_msgmnb=65536
set msgsys:msginfo_msgmni=256
set msgsys:msginfo_msgssz=16
set msgsys:msginfo_msgtql=512
set msgsys:msginfo_msgseg=8192
* Semaphores
set semsys:seminfo_semmap=64
set semsys:seminfo_semmni=1024
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmnu=1024
set semsys:seminfo_semmsl=300
set semsys:seminfo_semume=64
* Shared memory
set shmsys:shminfo_shmmni=220
set shmsys:shminfo_shmseg=100

2. The backup that followed the reboot is yielding the same results.
