If you are interested in polling because of performance, you should really consider using click-userspace with netmap (currently on FreeBSD, but linux support is really close now) http://info.iet.unipi.it/~luigi/netmap/ In our tests it seems to beat in-kernel click by a factor of 2, for I/O intensive tasks (where polling makes the difference). http://info.iet.unipi.it/~luigi/netmap/20110729-rizzo-infocom.pdf cheers luigi _______________________________________________ click mailing list [email protected] https://amsterdam.lcs.mit.edu/mailman/listinfo/click
