Its FTP Performance under Win95/Linux is about 700-800KByte/sec against the ftp server connected to the same HUB. When I use this card on FreeBSD-3.1, it only performs in about 300KByte/sec for the same configuration. In addition, when I ping FreeBSD machine (allegro) on the same time pinging another machine (Sun Ultra-1), the RTTs against FreeBSD box showes larger variance (from 0.6ms upto 150ms). 'ifconfig xl0 media autoselect' produces following message.
