Hello guys,

We are runnig an adsm 3.1.2.90 server on AIX 4.3.3 and we have AIX clients
4.3.
The clients are connected with 100MB Ethernet Full Duplex to the server.
The client in this example is an S70, 12 GB Memory and 8 processors.

We archive a lot of oracle database files and some output is;

Normal File-->   2,065,702,912 /oradata/xsb01/d0101f01/01.dbf  [Sent]
Archive processing of "01.dbf" finished without failure.

Total number of objects inspected:           1
Total number of objects archived:             1
Total number of objects updated:              0
Total number of objects rebound:              0
Total number of objects deleted:               0
Total number of objects failed:                  0
Total number of bytes transferred:     723.58  MB
Data transfer time:                            70.09  sec
Network data transfer rate:          10,570.64  KB/sec
Aggregate data transfer rate:         1,154.29  KB/sec
Objects compressed by:                       64%
Elapsed processing time:             00:10:41

So we backup 2 GB files in about 10 minutes, I think this is slow.
My question is: why is the difference between - the elapsed processing time
and the data transfer time - so big
We are compressing on the client as you see!
Is there a problem with compressing the data? Are there some wrong settings
in AIX or ADSM?? such as VMTUNE or the NO -a settings????


WHO can help me???
