I see this "sawtooth" behaviour as well. Mac OS X obviously uses a big cache for network sending (128 KB?) and the ftp client reports the speed of the data going into the cache, not the speed of the data going actually over the wire (phone cable). So, the "pauses" you see is when the cache is filled but still in the process of being sent. With a 64 kbit line, those pauses are so long that the ftp CLI client assumes a stalled connection.


Nevertheless, this is more an optical glitch. The overall speed (total file size divided by total sending time) should be about the same as with Mac OS 9. It's about 7.3 K/sec over a 64 kbit line here.


i am a totally kernel newbie,

On Mac OS X, there is next to never the need to tune the kernel. Surely not to satify a 64 kbit network connection.


the gui sux, it mounts the share read only.

The GUI? Which GUI?

If you are talking about the Finder, it's a known limitation of the Finder to handle FTP connections read-only. You'll have to resort to some other FTP client until Apple has fixed this. There are plenty of them: curl, wget, ftp, RBBrowser, Transmit, Fetch, Internet Explorer[1], Camino[1], FireFox[1], ...

[1] Not sure wether these allow FTP upload but I'd test them if the others don't satisfy you.
