Subject: [0/14] GRO: Lots of microoptimisations
Date: Wed, 27 May 2009 14:45:39 +1000 [thread overview]
Message-ID: <20090527044539.GA32372@gondor.apana.org.au> (raw)
Hi Dave:
This series of patches brings GRO performance to within 1% of LRO
on the slow machine that I was testing. I can overtake LRO by
deleting the IP checksum test and the Ethernet header test from
GRO, which LRO doesn't do anyway, but that's not very nice :)
I'm still looking at other optimisations as time allows.
Cheers,
