It is currently connected by just one of it's two gig ethernet ports. I also have two cisco switches with an etherchannel between them (using 2 x gig ports on each switch). I would like to connect the remaining NIC on my FreeBSD box to the other switch and enable 802.3ad on those switch ports to aggregate traffic between them. This is in the hope that it can better serve multiple FTP clients. Is my thinking correct? Other than the network interface changes which are documented here: http://www.freebsd.org/doc/handbook/network-aggregation.html are there any further tweaks I could make to improve things? -the server is a 'standard install' and does not use ZFS. It has an adaptec 5408 RAID card with 4 x SATA II drives and, IIRC, 128K stripe size and plenty of RAM. Is there a way of testing this other than initiating large file transfers to this server from multiple hosts? Many thanks, Matt.
