problem with ethernet update rates

dolo · 08-12-2009, 05:22 AM

i am communicating between 2 pcs on ethernet using TCP/IP. the update used is @ 50 msec. but it is observed that the user thread shows update not @ 50 msec exactly but beyond this because of some daemon process running in back ground which i do not know. because of this at every 1 sec time period the update is not exactly 50 msec but more than this. this is cyclic problem @ 1 sec.
pl. help to sort out the same.

Code:

ifconfig <interface>

check for frame, carrier, drops, or just plain errors.

then

Code:

mii-tool -v interface

check you are set to correct negotiation and duplex as neighbour/link partner
