Hi Dirk,

It seems, our BSP is not using the End driver. I don't have a sysEnd.c
file. I have a configNet.h file, that defines a network config string:

You probably are using and end driver, it just doesn't use the setup I
described. Your load string defines the parameter you need to modify.
Change this:
#define DEC_LOAD_STRING "0xfe020000:0x0:0x12:0x12:-1:-1:-1:0:0x80000000"

into this:
#define DEC_LOAD_STRING "0xfe020000:0x0:0x12:0x12:128:-1:-1:0:0x80000000"
The individual parameters are described in the vxWorks documentation for
the dec21x40End library (section 1), which explains that the default vaue
for <nrds> is 32; increasing that should significantly improve your NFS
performance on a busy network.
Note that in recent versions of the driver (provided with WRS patches or a
recent version of Tornado), there are several more optional parameters
that can control the network MII phy interface. These may not be
documented other than in the source code.
