OK, Eero, what if I have a lengthy DSCOPY going on between two HP machines? or
continuous spooling over the LANIC between HP machines? or JetDirect over
a network or... you get the picture.  Lanic isn't just for NS/VT.
 
Now, lets say ping returns lengthy responses off our machine, is it a CPU
problem or LANIC problem or both?
 
How can you determine factors that affect network response? What tools are at
my disposal to check LANIC rates or problems?
 
Also, if a LANIC saturates from network services, is there an upgrade path to
LANIC?
