Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk On one of our development machines we are running wu-ftpd. When FTP'ing over a T-3 to a PPP (28.8kbaud) line from a PPro 200 to it we were seeing as low as 2.0k/second. Yet, FTP'ing from a Sun 4/75 we were seeing 2.8kbaud solid performance. It appears to be [by watching modem lights] that the BSD box isn't streaming in the sense of a continuous send or receive while receiving acks along the way. The Sun boxes [all of them] seem to do this out of the box. I verified this behavior on ftp.cdrom.com and random SunOS boxes. Any ideas how to make the BSD behavior more like the SunOS? Thanks, -Tomas
