Ken,
Looks like we have some more tuning to do. Thanks for your help on this - it
is greatly appreciated.

The hardware ethernet adapter parameters for 100 Mb/s should be set as
follows:
transmit queue size = 16384 (the maximum)
hardware receive queue size = 2048 (the maximum)
media speed = 100_Full_Duplex
The no parameters should be set as follows:
thewall = maximum
sb_max = 1048576
tcp_sendspace = 32768
tcp_recvspace = 32768
udp_sendspace = 56296 (or more)
udp_recvspace = 262144 ( or more) (For NetView, this is one of the most
important parameters to make as big as possible since all traps are udp
packets.
tcp_mssdflt = 1500 (for ethernet adapter)
rfc1323 = 1
In addition, set /usr/samples/kernel/vmtune -p 5 -P 5.
Ensure that you have the correct amount of paging space, i.e. for up to 2Gb
memory, then 2-3 Gb paging space.
Regards,
ken
