Follow-up Comment #15, patch #7060 (project lwip):

The improvement will be greater with non-caching processors or if the data
falls out of the cache.  The better the caching the lower the gain as your PC
test indicates.  I am working on an lwIP 8-bit port to a non-caching processor
and will add those results.

I agree about this going in and not with an option.  It may be slightly
larger in code size but there's no way it could be slower.
