See the TSM 5.3 Performance guide for recommended values of eg TCPWINDOWSIZE, 
which can improve the performance.
 
But an additional question I just was dealing with. The file system backup 
handles each domain sequentially, first the backup of domain A, then the backup 
of domain B and so on. Can the backup of eg 4 domains be started simultaneously 
if the backup goes to a diskpool. Might have to check the manual on 
RESOURCEUTILIZATION first.
 
best regards,
Kurt

hi, i have a question :

any ideas how to speed up AIX client backup of  8,259,711 files ?
it's not about size , these 8 mil files have cca. 3GB even less ...

client aix 5.2 via TCP network LAN to aix 5.2 with TSM 5.3.1.4
with SATA cache pools ... data compression forced by server

Elapsed processing time: 12:40:47
objects compressed by LOUSY 17%

it can be it, right ? anyone has something similar ? i hope yes :-)

thanks
goran

PS: i'll try to "off" data compression when the node will not be accessing
server, which is rarely ... LOOL
