Re: bonding question

Tat,

Channel bonding may only be useful in situations where you want to
aggregate your large bandwidth needs, like file servers.  In my OM
cluster I channel bonded our head node and the NFS fileserver and got
some speedup in performance on our applications, but the channel bonding
on the individual nodes didn't give much.

Tat-
 Channel bonding does not so much double you speed as it doubles yhe
size of you pipe. In teh case of openmosix, you will see little to
gain in small data transfers, when moving large amounts of data, say
movie streams or several files at once then you will notice teh
difference. Kind like when driving, If you have only one bridge at 50
mph it takes a long time for everyone to get across, even if youmove
it up to a 100mph it is still going ot take long time to get everyone
across, becuase it is a choke point, but if you add a second bridge
everyone still crosses at 50 but more people are crossing at the same
time.
