Attention
Set this parameter to ON only if you are absolutely sure your backup strategy
enables you to restore a file which has been deleted.

5.3.1.11 Enable Disk Read After Write Verify

In NetWare, this read-after-write verify capability complements the hot fix
function. This allows the system to prevent any file from being written to a bad
disk block by attempting to read the data after it has been written to disk.
NetWare′s read-after-write capability and hot fix function are implemented in
software.
This value is normally determined by the device driver and normally defaults to
ON.
On all IBM disk controllers, this read-after-write operation is completed at the
hardware level. Leaving this parameter ON will degrade disk subsystem
performance.
You can modify this value using the set command in the AUTOEXEC.NCF file as
follows:

SET ENABLE READ AFTER WRITE VERIFY=VALUE

NetWare 3.12 and 4.1:
Default = ON
This value can be viewed and set by using the MONITOR.NLM utility.
5.3.2 Network Subsystem
Poor network design or network traffic congestion can have an adverse effect on
the server and workstation performance. The following sections highlight some
important factors to consider in order to optimize the performance of the network
subsystem.

5.3.2.1 LAN Device Driver Efficiency

The device driver is responsible for communicating between the NetWare
operating system and the LAN adapter hardware. It assembles and
disassembles the IPX packets on the LAN as they come through the driver.
The NetWare device drivers produced by IBM and Novell are checked for
performance before they are released. If they do not perform better (or at least
as fast as the old driver), they are not released. Therefore, always use the latest
device driver unless otherwise stated.
Some of the software LAN adapter device drivers are written with command line
options which can be used to change the behavior of the device driver. For
example, some third party manufacturers have a command line option to switch
the early token release option on or off. This option is available on most 16
Mbps token-ring adapters.
