3 years ago I had a linux machine with a less powerfull cpu maxing out the interface with SMB transfers. In all available enviroments under a 100mbit switch I can max out the interfaces using Windows or Linux. On my particular enviroment (a 3com switch at home) I can max out the interfaces doing transfers between my laptop and my home pc, both running XP. -- Joao Barros _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
