6.0 and 7.x share the same code so the settings are identical. As to
downside you pay a penalty if the fastforwarding code has to hand the
packet back to the "slow path". There may also be side effects from the
run-to-completion model it uses. You should test to decide if the
feature is worth enabling for your environment. I'm not sure it's had
much testing (Andre?).
When activated on a router it gives a very nice speed boost. Process
completion pays off very well here. It has got a lot of testing at
various ISP's on their production routers. For hosts it doesn't really
hurt but is totally pointless.
Andre, many thanks to both you and Sam. I will definitely do some
testing this weekend. Speaking of weekends, have a great one.
