As this looks the easiest one from the set of options presented by
David and Paul, I want to go with this first.

I have 2x Intel X5335 Quad core machine running linux-22.214.171.124 +
Please comment on this with respect to need for right combination of
kernels and stacks.

So here nhelpers should be 9 (2 x Quad +1).
This will help me in supporting more number of tunnel creation at a time.
However, how can I speed up IPSec packet processing in KLIPS (the
Does it require any special configuration in
kernel/KLIPS/pluto/network/anything specific to multicore?
Or the SMP kernel itself will balance the processing among different
cores and will help me achieve the 1Gig figure?
Thanks for your time.
