We've just installed ADSM/MVS 3.1 on our TCP/IP 3.2 Ethernet network
over ATM (LANE) backbone.  We have the lastest ADSM 3.x client code on
our HP-UX 10.2 & IBM AIX 4.3 servers.
In the dsmsched.log I am seeing:
Network data transfer rate:        1,772.97 KB/sec
Aggregate data transfer rate:      1,468.25 KB/sec
We do not have ADSM compression turned on as we are using hardware
compression on our 3494/3590 MagStar tape drives.
Our TCPIP/MVS 3.2, the  LARGEDATABUFFERPOOLSIZE is set to 32768.
In the HP / AIX Clients' the dsm.sys parameters are:
   TCPWindowsize      64
   TCPBuffsize             32
   TXNBytelimit       2048
Any help in identifying critical tuning points will be appreciated!
