But HOW?! GPU has very high "preparation" and data transfer cost,
how it could be used for such small packets of data, as 1.5-9K
datagrams?!
According to
http://www.ndsl.kaist.edu/~kyoungsoo/papers/packetshader.pdf -
cumulative dispatch latency is between 3.8-4.1 microseconds (section 2.2).
And GPU is doing routing lookup only (at least for IPv4/IPv6
forwarding), so we're always transferring/receving fixed amount of data.
Btw, there are exact hardware specifications in this document.
