I think its a windowism, stands for Receive Side Scaling, and what it means is multiple receive queues, each with an MSI/X vector so they can interrupt different CPUs, or they can be tied to virtual guests, or MACs, etc etc...
AFAICT FreeBSD can't currently benefit from this as there is no cpu affinity for connections. I may be wrong, but I see lower single-connection throughput using a receive queue per core than using a single receive queue. RSS is done by hashing a TCP tuple (I'm deliberately vague because at least with cxgb there are multiple combinations, the default is the standard 4-tuple) to a receive queue. -Kip _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
