Afrose,

	Do you have any details on "good" figures to pick and add to a
standard box to increase routing speed, bandwidth, overall network behavior?
I have info on some settable commands but no idea what figures to use,
128,256, 1 million, etc.
this is an example of some stuff I grabbed from books but leave them
inactivated.


*       set hme0:tcp_xmit_hiwat=65535
*       set hme0:tcp_recv_hiwat=65535
*       set hme0:tcp_cwnd_hiwat=65534
*       set hme0:nautopush=32
*       set hme0:maxusers=40
*       set hme0:max_nprocs=2048
*       set hme0:maxuprc=100
*       set hme0:ncsize=10240
*       set hme0:ufs_inode=10240
