We have usually set the following to get more performance on our NetWare
clients.
1.1. Max Directory Cache Buffers 6,000
1.2. Min Directory Cache Buffers 2,000
1.3. Max Packet Receive Buffers 10,000
1.4. Min Packet Receive Buffers 2,000
1.5. Maximum concurrent disk writes 750 (this best practice but some set it
to 1000)
1.6. Maximum concurrent directory cache writes 150
We have also found it best to ensure the NIC is set to the correct speed and
duplex setting (i.e. 100 Full) not auto auto.
Being that I'm not a CNE and the above are Netware settings I would use caution
to ensure they will work on your servers. Or, maybe some CNE's on the list
might comment on the settings above.

Hi Eric
Your settings seems ok - I have a couple of questions to you:
Do you have compression enabled on the files in question?
Do you run antivirus on this server? if yes, which product?
Do you know config.nlm from Novell? If so you could use it, and I would be
happy to go through the config.txt for you?

Emne: Slow backup from Netware of small files
Dear All,
ENVIRONMENT
==============
TSM Server 5.2 on AIX 5.1
TXNGROUPMAX 256
TCPWINDOWSIZE 64
TSM Backup/Archive Client 5.2 on Netware 5
TSANDS.NLM ver 10110.95
TSA500.NLM ver 5.05d
SMDR.NLM ver 6.50c
TCPWINDOWSIZE 64
TCPBUFSIZE 32
LARGECOMMBUFFERS NO
TXNBYTELIMIT 25600
PROCESSORUTILIZATION 10
RESOURCEUTILIZATION 5
Gigabit Network
PROBLEM
=========
Whilst backup performance of large files is very good (approx 16 MB/s) the
backup performance of small files (50 KB to 300KB) is extremely poor (300
KB/s).
Backups are straight to a diskpool.
I'd be interested in hearing from anyone with any experience of successful
backup of small files in a Netware environment, or anyone who has any ideas
as to what might be done to improve the situation.
Thanks as always,
Eric Winters
