I see a few things that you might want to change. Here is a copy of my
dsm.sys file (notice the commethod line, the compression line===>you also
would want to turn compression to "client determine" on your client,
tcpnodelay, and tcpbuffsize) (remember shardmem only works locally). Hope
this helps
Servername d26bk001sh
COMMMethod SHAREdmem
SHMPort 1510
PASSWORDACCESS Generate
Inclexcl /usr/lpp/adsm/bin/inclexcl.txt
nodename d26bk001
TXNBytelimit 25600
TCPWindow 64
SCHEDLOGName /usr/lpp/adsm/bin/dsmsched.log
COMPression OFF
tcpnodelay YES
tcpbuffsize 32

Hi nolan,
I think if it is just the initial stages then you might want to
wait
for a few days more than jump into any arbitrary changes. in our case I did
observe that the first backup after an upgrade does take a longer time.
sincere regards
sri
