set the minimum packet receive buffers parameter in the startup.ncf
file to 1500 for each adapter in the system.
Set the maximum packet receive buffers to three times the minimum
packet receive buffers. Typically 4 MB of RAM is required per 1000
receive buffers. For more information, see “Verifying or Modifying
Adapter Parameters” on page 88.
12. In the autoexec.ncf file, delete the packet receive buffers parameter
(RxBuffers=32) in the load statement for this adapter. Deleting the
receive buffers phrase from the load statement resets the receive
buffers parameter to the default value of 200 for this adapter.
Note
The server needs to be restarted for the new configuration.
Example: The default maximum number of receive buffers for the system
is 500; the default minimum is 128. Edit the startup.ncf file to have the
following entries. The actual numbers will be a function of the number of
ports in the system. The following is an example for a system with 8 ports
installed:
set maximum packet receive buffers = 36000
set minimum packet receive buffers = 12000
