Re: 2-node RAC faster than 6-node!

Abdul,

The answer is SERIALIZATION.

Like someone (!)  mentioned RAC is like a stereo amplifier. The
outcome is dependent on the original music. If the original track has
lots of noise, that will also be amplified and i guess that is what
you are seeing.

What is your SR#.?
