Required features for 5.2-RELEASE

Significant parts of the network stack (especially IPv4 and IPv6) now have
fine-grained locking of their data structures. However, it is not yet
possible for the netisr threads to run without Giant, due to dependencies
on sockets, routing, etc. A 5.2-RELEASE goal is to have the network stack
running largely without Giant, which should substantially improve
performance of the stack, as well as other system components by reducing
contention on Giant.

Kann das der Grund fuer so schlechte Werte sein?

Anderswo habe ich auch etwas von ausstehenden Arbeiten Richtung zero-copy
im network stack gelesen, kann es aber gerade nicht finden.

Gruss
Peter
