Both machines are FreeBSD 8.2-stable with > istgt and the Onboard ISCSI initiator I've reached almost 118 MB/s but I don't have access to the configuration atm. This was from a windows 7 client. From vmware I've gotten 107 MB/s during a debian 6 server installation. I'll post the settings when I get back to work. You could verify that there are no mismatch between the nics. Have you tried a plain scp of a large file and some rsync of ie. the ports-tree (with distfiles)? -- regards Claus When lenity and cruelty play for a kingdom, the gentler gamester is the soonest winner.
