What did the tranfer rate show as?
1024 x 6.24 = 6389MB (megabyte)
Network is usually in Megabit, yes?
6389MB x 8 = 51112 (megabit)

This doc offers alot of information about improving performance. I'm
especially interested in this because it took 56 minutes to restore
6.24G
of data, from Novell server to Novell server, over a 100MB pipe.
Our TSM version is 5.1.1 ( I know,,,we need to upgrade)...and the
client
version is 5.2.
In the dsmserv.opt file the MIRRORWRITE DB = SEQUENTIAL. According to
this
doc, we'll get better performance is we change MIRRORWRITE DB to
PARALLEL.
I thought I would do this then add the DBPAGESHADOW = YES parameter.
(the
MIRRORWRITE LOG = PARALLEL)
My plan is to make small changes to see if there is an impact, positive
or
negative. We have 2G of virtual memory, so I changed the bufpoolsize
from
262144 to 524288 and thought I'd make the MIRRORWRITE DB change also.
Has anyone made these changes and seen any performance
improvements/degredations? Any experiences or advice is welcome.....
Thanks for any input,
Debbie
