Hi Rich,

first of all, thanks a lot for your reply.

For Windows or Linux clients, or both? Besides, have you (or anybody
else subscribed to this list) any recommendations for tuning on the
server side?

Yes, the phyiscal interface is set to GB, I notice this when I do an
SCP transfer (also encrypted, even stronger than plain old DES) to a
native ext3 fs where I get exactly the speeds you mentioned. So, I
suppose it's likely to be something else, i. e. not the setting of the
physical interface.

Yes, I know. But the settings are clearly GB on both sides (client and
sever).

Thanks in advance and kind regards,
