The stock settings are more than enough to saturate 100TX with even relatively ancient hardware. And by ancient I mean Pentium 2 class machines. The biggest tuning you can do is use intel (fxp) or 3com (xl) NICS and a halfway decent switch. If your server box can't saturate 100TX ethernet with the defaults then something is amiss. Perhaps provide a dmesg from the server and a client and a tcpdump from an FTP session between them? -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB
